  - containsKey
```
public boolean containsKey(Object key)
```
    Description copied from interface: IMap
    
    Returns true if this map contains an entry for the specified key.
    Warning:
    This method uses hashCode and equals of the binary form of the key, not the actual implementations of hashCode and equals defined in the key's class.
    Interactions with the map store
    If key is not found in memory MapLoader.load(Object) is invoked to load the value from the map store backing the map. Exceptions thrown by load fail the operation and are propagated to the caller.
    
    Specified by:

  - get
```
public V get(Object key)
```
    Description copied from interface: IMap
    Returns the value for the specified key, or null if this map does not contain this key.
    Warning 1:
    This method returns a clone of the original value, so modifying the returned value does not change the actual value in the map. You should put the modified value back to make changes visible to all nodes.
```
      V value = map.get(key);
      value.updateSomeProperty();
      map.put(key, value);
 
```
    Warning 2:
    This method uses hashCode and equals of the binary form of the key, not the actual implementations of hashCode and equals defined in the key's class.
    Interactions with the map store
    If value with key is not found in memory MapLoader.load(Object) is invoked to load the value from the map store backing the map. Exceptions thrown by load fail the operation and are propagated to the caller.
    Specified by:
    
    get in interface BaseMap<K,V>

protected Object getInternal(Object key)
```
  - put
```
public V put(K key,
             V value)
```
    Description copied from interface: IMap
    
    Associates the specified value with the specified key in this map. If the map previously contained a mapping for the key, the old value is replaced by the specified value.
    Warning 1:
    This method returns a clone of the previous value, not the original (identically equal) value previously put into the map.
    Warning 2:
    This method uses hashCode and equals of the binary form of the key, not the actual implementations of hashCode and equals defined in the key's class.
    
    Note: Use IMap.set(Object, Object) if you don't need the return value, it's slightly more efficient.
    Interactions with the map store
    If no value is found with key in memory, MapLoader.load(Object) is invoked to load the value from the map store backing the map. Exceptions thrown by load fail the operation and are propagated to the caller.
    If write-through persistence mode is configured, before the value is stored in memory, MapStore.store(Object, Object) is called to write the value into the map store. Exceptions thrown by store fail the operation and are propagated to the caller.
    If write-behind persistence mode is configured with write-coalescing turned off, ReachedMaxSizeException may be thrown if the write-behind queue has reached its per-node maximum capacity.
    
    Specified by:
    
    put in interface BaseMap<K,V>
    
    Specified by:

    Parameters:
    
    key - The specified key.
    
    value - The value to associate with the key.
    
    Returns:
    
    Previous value associated with key or null if there was no mapping for key.
  - remove
```
public V remove(Object key)
```
    Description copied from interface: IMap
    
    Removes the mapping for a key from this map if it is present.
    If you don't need the previously mapped value for the removed key, prefer to use IMap.delete(java.lang.Object) and avoid the cost of serialization and network transfer.
    Warning 1:
    This method uses hashCode and equals of the binary form of the key, not the actual implementations of hashCode and equals defined in the key's class.
    Warning 2:
    This method returns a clone of the previous value, not the original (identically equal) value previously put into the map.
    Interactions with the map store
    If no value is found with key in memory, MapLoader.load(Object) is invoked to load the value from the map store backing the map. Exceptions thrown by load fail the operation and are propagated to the caller.
    If write-through persistence mode is configured, before the value is removed from the memory, MapStore.delete(Object) is called to remove the value from the map store. Exceptions thrown by delete fail the operation and are propagated to the caller.
    If write-behind persistence mode is configured with write-coalescing turned off, ReachedMaxSizeException may be thrown if the write-behind queue has reached its per-node maximum capacity.

```
public boolean remove(Object key,
                      Object value)
```
    Description copied from interface: IMap
    Removes the entry for a key only if currently mapped to a given value. This is equivalent to
```
   if (map.containsKey(key) && map.get(key).equals(value)) {
       map.remove(key);
       return true;
   } else return false;
```
    except that the action is performed atomically.
    Warning:
    This method uses hashCode and equals of the binary form of the key, not the actual implementations of hashCode and equals defined in the key's class.
    Interactions with the map store
    If no value is found with key in memory, MapLoader.load(Object) is invoked to load the value from the map store backing the map. Exceptions thrown by load fail the operation and are propagated to the caller.
    If write-through persistence mode is configured, before the value is removed from the memory, MapStore.delete(Object) is called to remove the value from the map store. Exceptions thrown by delete fail the operation and are propagated to the caller.

  - removeAll
```
public void removeAll(Predicate<K,V> predicate)
```
    Description copied from interface: IMap
    
    Removes all entries which match with the supplied predicate.
    If this map has index, matching entries will be found via index search, otherwise they will be found by full-scan.
    Note that calling this method also removes all entries from callers Near Cache.
    Interactions with the map store
    If write-through persistence mode is configured, before a value is removed from the memory, MapStore.delete(Object) is called to remove the value from the map store. Exceptions thrown by delete fail the operation and are propagated to the caller.
    If write-behind persistence mode is configured with write-coalescing turned off, ReachedMaxSizeException may be thrown if the write-behind queue has reached its per-node maximum capacity.
    
    Specified by:
    
    removeAll in interface IMap<K,V>
    
    Parameters:
    
    predicate - matching entries with this predicate will be removed from this map
  - removeAllInternal
```
protected void removeAllInternal(Predicate predicate)
```
  - delete
```
public void delete(Object key)
```
    Description copied from interface: IMap
    
    Removes the mapping for the key from this map if it is present.
    Unlike IMap.remove(Object), this operation does not return the removed value, which avoids the serialization and network transfer cost of the returned value. If the removed value will not be used, this operation is preferred over the remove operation for better performance.
    The map will not contain a mapping for the specified key once the call returns.
    Warning:
    This method breaks the contract of EntryListener. When an entry is removed by delete(), it fires an EntryEvent with a null oldValue.
    Also, a listener with predicates will have null values, so only keys can be queried via predicates.
    Interactions with the map store
    If write-through persistence mode is configured, before the value is removed from the the memory, MapStore.delete(Object) is called to remove the value from the map store. Exceptions thrown by delete fail the operation and are propagated to the caller.
    If write-behind persistence mode is configured with write-coalescing turned off, ReachedMaxSizeException may be thrown if the write-behind queue has reached its per-node maximum capacity.

    Description copied from interface: IMap
    
    If this map has a MapStore, this method flushes all the local dirty entries.
    Interactions with the map store
    Calls MapStore.storeAll(Map) and/or MapStore.deleteAll(Collection) with elements marked dirty. Please note that this method has effect only if write-behind persistence mode is configured. If the persistence mode is write-through calling this method has no practical effect, but an operation is executed on all partitions wasting resources.

    Description copied from interface: IMap
    
    Same as #put(K, V, long, java.util.concurrent.TimeUnit) except that the map store, if defined, will not be called to load/store/persist the entry.
    The entry will expire and get evicted after the TTL. If the TTL is 0, then the entry lives forever. If the TTL is negative, then the TTL from the map configuration will be used (default: forever).
    Warning 1:
    This method uses hashCode and equals of the binary form of the key, not the actual implementations of hashCode and equals defined in the key's class.
    Warning 2:
    Time resolution for TTL is seconds. The given TTL value is rounded to next closest second value.

    Description copied from interface: IMap
    If the specified key is not already associated with a value, associate it with the given value. This is equivalent to
```
   if (!map.containsKey(key))
       return map.put(key, value);
   else
       return map.get(key);
```
    except that the action is performed atomically.
    Note:
    This method uses hashCode and equals of the binary form of the key, not the actual implementations of hashCode and equals defined in the key's class.
    Also, this method returns a clone of the previous value, not the original (identically equal) value previously put into the map.
    Interactions with the map store
    If no value is found with key in memory, MapLoader.load(Object) is invoked to load the value from the map store backing the map. Exceptions thrown by load fail the operation and are propagated to the caller.
    If write-through persistence mode is configured, before the value is stored in memory, MapStore.store(Object, Object) is called to write the value into the map store. Exceptions thrown by the store fail the operation and are propagated to the caller.
    If write-behind persistence mode is configured with write-coalescing turned off, ReachedMaxSizeException may be thrown if the write-behind queue has reached its per-node maximum capacity.

    This method uses hashCode and equals of the binary form of the key, not the actual implementations of hashCode and equals defined in the key's class.
    Warning 2:
    This method may return false even if the operation succeeds.
    Background: If the partition owner for given key goes down after successful value replace, but before the executing node retrieved the invocation result response, then the operation is retried. The invocation retry fails because the value is already updated and the result of such replace call returns false. Hazelcast doesn't guarantee exactly once invocation.

```
public void lock(K key)
```
    Description copied from interface: IMap
    
    Acquires the lock for the specified key.
    If the lock is not available, then the current thread becomes disabled for thread scheduling purposes and lies dormant until the lock has been acquired.
    You get a lock whether the value is present in the map or not. Other threads (possibly on other systems) would block on their invoke of lock() until the non-existent key is unlocked. If the lock holder introduces the key to the map, the put() operation is not blocked. If a thread not holding a lock on the non-existent key tries to introduce the key while a lock exists on the non-existent key, the put() operation blocks until it is unlocked.
    Scope of the lock is this map only. Acquired lock is only for the key in this map.
    Locks are re-entrant so if the key is locked N times then it should be unlocked N times before another thread can acquire it.
    There is no lock timeout on this method. Locks will be held infinitely.

    This method uses hashCode and equals of the binary form of the key, not the actual implementations of hashCode and equals defined in the key's class.

```
    Description copied from interface: IMap
    
    Adds a MapListener for this map. To receive an event, you should implement a corresponding MapListener sub-interface for that event.
    Note that entries in distributed map are partitioned across the cluster members; each member owns and manages the some portion of the entries. Owned entries are called local entries. This listener will be listening for the events of local entries. Let's say your cluster has member1 and member2. On member2 you added a local listener and from member1, you call map.put(key2, value2). If the key2 is owned by member2 then the local listener will be notified for the add/update event. Also note that entries can migrate to other nodes for load balancing and/or membership change.

    The set is NOT backed by the map, so changes to the map are NOT reflected in the set, and vice-versa.
    This method is always executed by a distributed query, so it may throw a QueryResultSizeExceededException if GroupProperty.QUERY_RESULT_SIZE_LIMIT is configured.
    
    Specified by:
    
    localKeySet in interface IMap<K,V>
    
    Parameters:
    
    predicate - specified query criteria
    
    Returns:
    
    keys of matching locally owned entries
    
    See Also:

  - addIndex
```
public void addIndex(String attribute,
                     boolean ordered)
```
    Description copied from interface: IMap
    Adds an index to this map for the specified entries so that queries can run faster.
    Let's say your map values are Employee objects.
```
   public class Employee implements Serializable {
     private boolean active = false;
     private int age;
     private String name = null;
     // other fields

     // getters setter
   }
 
```
    If you are querying your values mostly based on age and active then you should consider indexing these fields.
```
   IMap imap = Hazelcast.getMap("employees");
   imap.addIndex("age", true);        // ordered, since we have ranged queries for this field
   imap.addIndex("active", false);    // not ordered, because boolean field cannot have range
 
```
    Index attribute should either have a getter method or be public. You should also make sure to add the indexes before adding entries to this map.
    Time to Index
    Indexing time is executed in parallel on each partition by operation threads. The Map is not blocked during this operation.
    The time taken in proportional to the size of the Map and the number Members.
    Searches while indexes are being built
    Until the index finishes being created, any searches for the attribute will use a full Map scan, thus avoiding using a partially built index and returning incorrect results.
    Specified by:
    
    addIndex in interface IMap<K,V>
    
    Parameters:
    
    attribute - index attribute of value
    
    ordered - true if index should be ordered, false otherwise.
  - getLocalMapStats
```
public LocalMapStats getLocalMapStats()
```
    Description copied from interface: IMap
    
    Returns LocalMapStats for this map.
    LocalMapStats are the statistics for the local portion of this distributed map and contains information such as ownedEntryCount backupEntryCount, lastUpdateTime, lockedEntryCount.
    Since this stats are only for the local portion of this map, if you need the cluster-wide MapStats then you need to get the LocalMapStats from all members of the cluster and combine them.
    
    Specified by:
    
    getLocalMapStats in interface IMap<K,V>
    
    Returns:
    
    this map's local statistics
  - executeOnKey
```
public Object executeOnKey(K key,
                           EntryProcessor entryProcessor)
```
    Description copied from interface: IMap
    Applies the user defined EntryProcessor to the entry mapped by the key. Returns the object which is the result of the EntryProcessor#process(Entry) method.
    The EntryProcessor may implement the Offloadable and ReadOnly interfaces.
    If the EntryProcessor implements the Offloadable interface the processing will be offloaded to the given ExecutorService allowing unblocking of the partition-thread, which means that other partition-operations may proceed. The key will be locked for the time-span of the processing in order to not generate a write-conflict. In this case the threading looks as follows:
    1. partition-thread (fetch & lock)
    2. execution-thread (process)
    3. partition-thread (set & unlock, or just unlock if no changes)
    If the EntryProcessor implements the Offloadable and ReadOnly interfaces the processing will be offloaded to the given ExecutorService allowing unblocking the partition-thread. Since the EntryProcessor is not supposed to do any changes to the Entry the key will NOT be locked for the time-span of the processing. In this case the threading looks as follows:
    1. partition-thread (fetch & lock)
    2. execution-thread (process)
    In this case the EntryProcessor.getBackupProcessor() has to return null; otherwise an IllegalArgumentException exception is thrown.
    If the EntryProcessor implements only ReadOnly without implementing Offloadable the processing unit will not be offloaded, however, the EntryProcessor will not wait for the lock to be acquired, since the EP will not do any modifications.
    Using offloading is useful if the EntryProcessor encompasses heavy logic that may stall the partition-thread.
    If the EntryProcessor implements ReadOnly and modifies the entry it is processing an UnsupportedOperationException will be thrown.
    Offloading will not be applied to backup partitions. It is possible to initialize the EntryBackupProcessor with some input provided by the EntryProcessor in the EntryProcessor.getBackupProcessor() method. The input allows providing context to the EntryBackupProcessor - for example the "delta" so that the EntryBackupProcessor does not have to calculate the "delta" but it may just apply it.
    See IMap.submitToKey(Object, EntryProcessor) for an async version of this method.
    Interactions with the map store
    If value with key is not found in memory MapLoader.load(Object) is invoked to load the value from the map store backing the map. Exceptions thrown by load fail the operation and are propagated to the caller.
    If the entryProcessor updates the entry and write-through persistence mode is configured, before the value is stored in memory, MapStore.store(Object, Object) is called to write the value into the map store. Exceptions thrown by store fail the operation are propagated to the caller.
    If the entryProcessor updates the entry's value to null value and write-through persistence mode is configured, before the value is removed from the memory, MapStore.delete(Object) is called to delete the value from the map store. Exceptions thrown by delete fail the operation are propagated to the caller.
    If write-behind persistence mode is configured with write-coalescing turned off, ReachedMaxSizeException may be thrown if the write-behind queue has reached its per-node maximum capacity.

    For each entry not found in memory MapLoader.load(Object) is invoked to load the value from the map store backing the map. Exceptions thrown by load fail the operation and are propagated to the caller.
    If write-through persistence mode is configured, for each entry updated by the entryProcessor, before the updated value is stored in memory, MapStore.store(Object, Object) is called to write the value into the map store. Exceptions thrown by store fail the operation and are propagated to the caller.
    If write-through persistence mode is configured, for each entry updated to null value, before the value is removed from the memory, MapStore.delete(Object) is called to delete the value from the map store. Exceptions thrown by delete fail the operation and are propagated to the caller.
    If write-behind persistence mode is configured with write-coalescing turned off, ReachedMaxSizeException may be thrown if the write-behind queue has reached its per-node maximum capacity.

```
    Description copied from interface: IMap
    
    Puts an entry into this map without returning the old value (which is more efficient than put()).
    Warning 1:
    This method breaks the contract of EntryListener. When an entry is updated by set(), it fires an EntryEvent with a null oldValue.
    Warning 2:
    This method uses hashCode and equals of the binary form of the key, not the actual implementations of hashCode and equals defined in the key's class.

public void putAll(Map<? extends K,? extends V> map)
```
    Description copied from interface: IMap
    
    No atomicity guarantees are given. It could be that in case of failure some of the key/value-pairs get written, while others are not.
    Interactions with the map store
    For each element not found in memory MapLoader.load(Object) is invoked to load the value from the map store backing the map, which may come at a significant performance cost. Exceptions thrown by load fail the operation and are propagated to the caller. The elements which were added before the exception was thrown will remain in the map, the rest will not be added.
    If write-through persistence mode is configured, MapStore.store(Object, Object) is invoked for each element before the element is added in memory, which may come at a significant performance cost. Exceptions thrown by store fail the operation and are propagated to the caller. The elements which were added before the exception was thrown will remain in the map, the rest will not be added.
    If write-behind persistence mode is configured with write-coalescing turned off, ReachedMaxSizeException may be thrown if the write-behind queue has reached its per-node maximum capacity.

public void clear()

    Description copied from interface: IMap
    
    Clears the map and deletes the items from the backing map store.
    The MAP_CLEARED event is fired for any registered listeners. See MapClearedListener.mapCleared(MapEvent).
    To clear the map without removing the items from the map store, use IMap.evictAll().
    Interactions with the map store
    Calls MapStore.deleteAll(Collection) on each partition with the keys that the given partition stores. Exceptions thrown by deleteAll() are not propagated to the caller.

public Iterator<Map.Entry<K,V>> iterator(int fetchSize,
                                         int partitionId,
                                         boolean prefetchValues)
```
    Returns an iterator for iterating entries in the partitionId. If prefetchValues is true, all values will be sent along with the keys and no additional data will be fetched when iterating. If false, the values will be fetched when iterating the entries.
    The values are not fetched one-by-one but rather in batches. You may control the size of the batch by changing the fetchSize parameter. A too small fetchSize can affect performance since more data will have to be sent to and from the partition owner. A too high fetchSize means that more data will be sent which can block other operations from being sent, including internal operations. The underlying implementation may send more values in one batch than fetchSize if it needs to get to a "safepoint" to later resume iteration.
    NOTE Iterating the map should be done only when the IMap is not being mutated and the cluster is stable (there are no migrations or membership changes). In other cases, the iterator may not return some entries or may return an entry twice.
    
    Parameters:
    
    fetchSize - the size of the batches which will be sent when iterating the data
    
    partitionId - the partition ID which is being iterated
    
    Returns:
    
    the iterator for the projected entries

                                Predicate<K,V> predicate)
```
    Returns an iterator for iterating the result of the projection on entries in the partitionId which satisfy the predicate. The Iterator.remove() method is not supported and will throw an UnsupportedOperationException.
    The values are not fetched one-by-one but rather in batches. You may control the size of the batch by changing the fetchSize parameter. A too small fetchSize can affect performance since more data will have to be sent to and from the partition owner. A too high fetchSize means that more data will be sent which can block other operations from being sent, including internal operations. The underlying implementation may send more values in one batch than fetchSize if it needs to get to a "safepoint" to later resume iteration. Predicates of type PagingPredicate are not supported.
    NOTE Iterating the map should be done only when the IMap is not being mutated and the cluster is stable (there are no migrations or membership changes). In other cases, the iterator may not return some entries or may return an entry twice.
    
    Type Parameters:
    
    R - the return type
    
    Parameters:
    
    fetchSize - the size of the batches which will be sent when iterating the data
    
    partitionId - the partition ID which is being iterated
    
    projection - the projection to apply before returning the value. null value is not allowed
    
    predicate - the predicate which the entries must match. null value is not allowed
    
    Returns:
    
    the iterator for the projected entries
    
    Throws:
    
    UnsupportedOperationException - if Iterator.remove() is invoked
    
    IllegalArgumentException - if the predicate is of type PagingPredicate

```
    Description copied from interface: com.hazelcast.internal.journal.EventJournalReader
    
    Reads from the event journal. The returned future may throw UnsupportedOperationException if the cluster version is lower than 3.9 or there is no event journal configured for this data structure.
    NOTE: Configuring evictions may cause unexpected results when reading from the event journal and there are cluster changes (a backup replica is promoted into a partition owner). See MapEventJournal or CacheEventJournal for more details.
    
    Specified by:
    
    readFromEventJournal in interface com.hazelcast.internal.journal.EventJournalReader<EventJournalMapEvent<K,V>>
    
    Type Parameters:
    
    T - the return type of the projection. It is equal to the journal event type if the projection is null or it is the identity projection
    
    Parameters:
    
    startSequence - the sequence of the first item to read
    
    maxSize - the maximum number of items to read
    
    partitionId - the partition ID of the entries in the journal
    
    predicate - the predicate which the events must pass to be included in the response. May be null in which case all events pass the predicate
    
    projection - the projection which is applied to the events before returning. May be null in which case the event is returned without being projected
    
    Returns:
    
    the future with the filtered and projected journal items
