```
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:
    
    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.
    Parameters:
    
    key - The specified key.
    
    Returns:
    
    The value for the specified 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:
    
    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.
    
    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.
  - put

             TimeUnit timeunit)
```
    Description copied from interface: IMap
    
    Puts an entry into this map with a given ttl (time to live) value. Entry will expire and get evicted after the ttl. If ttl is 0, then the entry lives forever.
    
    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.
    
    Warning-2:
    
    This method returns a clone of the previous value, not the original (identically equal) value previously put into the map.
    
    Warning 3:
    Time resolution for TTL is seconds. The given TTL value is rounded to the next closest second value.
    
    Parameters:
    
    key - key of the entry
    
    value - value of the entry
    
    ttl - maximum time for this entry to stay in the map 0 means infinite.

                      long timeout,
                      TimeUnit timeunit)
```
    Description copied from interface: IMap
    
    Tries to put the given key and value into this map within a specified timeout value. If this method returns false, it means that the caller thread could not acquire the lock for the key within the timeout duration, thus the put operation is not successful.
    
    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.
    
    Parameters:
    
    key - key of the entry.
    
    value - value of the entry.
    
    timeout - maximum time to wait.
    
    timeunit - time unit for the timeout.
    
    Returns:
    
    true if the put is successful, false otherwise.
  - putIfAbsent
```

                     V 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.

```
    Description copied from interface: IMap
    Replaces 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(oldValue)) {

    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.
    Parameters:
    
    key - The specified key.
    
    oldValue - Replace the key value if it is the old value.
    
    newValue - The new value to replace the old value.

    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.
    
    Warning-2:
    
    This method returns a clone of the previous value, not the original (identically equal) value previously put into the map.
    Parameters:
    
    key - The specified key.
    
    value - The value to replace the previous value.
    
    Returns:
    
    The previous value associated with key, or null if there was no mapping for key.
  - set
```
public void set(K key,
                V value)
```
    Description copied from interface: IMap
    
    Puts an entry into this map. Similar to the put operation except that set doesn't return the old value, which is more efficient.
    
    Warning:
    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.
    
    Parameters:
    
    key - key of the entry.
    
    value - value of the entry.
  - set
```
public void set(K key,

                long ttl,
                TimeUnit timeunit)
```
    Description copied from interface: IMap
    
    Puts an entry into this map with a given ttl (time to live) value. Entry will expire and get evicted after the ttl. If ttl is 0, then the entry lives forever. Similar to the put operation except that set doesn't return the old value, which is more efficient.
    
    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 the next closest second value.
    
    Parameters:
    
    key - key of the entry
    
    value - value of the entry
    
    ttl - maximum time for this entry to stay in the map 0 means infinite.
    
    timeunit - time unit for the ttl
  - remove
```
public V remove(Object key)
```
    Description copied from interface: IMap
    
    Removes the mapping for a key from this map if it is present.
    The map will not contain a mapping for the specified key once the call returns.
    
    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.
    
    Warning-2:
    
    This method returns a clone of the previous value, not the original (identically equal) value previously put into the map.
    
    Parameters:
    
    key - Remove the mapping for this key.
    
    Returns:
    
    The previous value associated with key, or null if there was no mapping for key.
  - remove
```
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.
    Parameters:
    
    key - The specified key.
    
    value - Remove the key if it has this value.
    
    Returns:
    
    true if the value was removed.
  - 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.
    
    Parameters:
    
    predicate - matching entries with this predicate will be removed from this map
  - delete
```
public void delete(Object key)
```
    Description copied from interface: IMap
    
    Removes the mapping for a key from this map if it is present (optional operation).
    
    Unlike IMap.remove(Object), this operation does not return the removed value, which avoids the serialization cost of the returned value.
    If the removed value will not be used, a delete operation is preferred over a 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.
    
    Parameters:
    
    key - key whose mapping is to be removed from the map.
  - containsKey
```
public boolean containsKey(Object key)
```
    Description copied from interface: IMap
    
    Returns true if this map contains an entry for the specified key.
    
    Warning:
    
    ˆ 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. The key will first be searched for in memory. If the key is not found, and if a key is attributed, a MapLoader will then attempt to load the key.
    
    Parameters:
    
    key - The specified key.
    
    Returns:
    
    true if this map contains an entry for the specified key.
  - containsValue

public boolean containsValue(Object value)
```
    Description copied from interface: IMap
  - lock
```
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.
    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.
    
    Parameters:
    
    key - key to lock.
  - lock
```
public void lock(Object key,

                 TimeUnit timeUnit)
```
    Description copied from interface: IMap
    
    Acquires the lock for the specified key for the specified lease time.
    After lease time, the lock will be released.
    
    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.
    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.
    
    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.
    
    Parameters:
    
    key - the key to lock.
    
    leaseTime - time to wait before releasing the lock.
    
    timeUnit - unit of time to specify lease time.
  - unlock
```
public void unlock(K key)
```
    Description copied from interface: IMap
    
    Releases the lock for the specified key. It never blocks and returns immediately.
    
    If the current thread is the holder of this lock, then the hold count is decremented. If the hold count is zero, then the lock is released. If the current thread is not the holder of this lock, then IllegalMonitorStateException is thrown.
    
    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.

                         long timeout,
                         TimeUnit timeunit)
```
    Description copied from interface: IMap
    
    Tries to remove the entry with the given key from this map within the specified timeout value. If the key is already locked by another thread and/or member, then this operation will wait the timeout amount for acquiring the lock.
    
    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.
    
    Parameters:
    
    key - key of the entry.
    
    timeout - maximum time to wait for acquiring the lock for the key.
    
    timeunit - time unit for the timeout.

  - addLocalEntryListener
```
public String addLocalEntryListener(MapListener listener)
```
    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.
    
    Parameters:
    
    listener - MapListener for this map.
    
    Returns:
    
    A UUID.randomUUID().toString() which is used as a key to remove the listener.

```
public String addPartitionLostListener(MapPartitionLostListener listener)
```
    Description copied from interface: IMap
    
    Adds a MapPartitionLostListener.
    The addPartitionLostListener returns a register ID. This ID is needed to remove the MapPartitionLostListener using the IMap.removePartitionLostListener(String) method.
    There is no check for duplicate registrations, so if you register the listener twice, it will get events twice. IMPORTANT: Please @see com.hazelcast.partition.PartitionLostListener for weaknesses. IMPORTANT: Listeners registered from HazelcastClient may miss some of the map partition lost events due to design limitations.
    
    Parameters:
    
    listener - the added MapPartitionLostListener.
    
    Returns:
    
    returns the registration ID for the MapPartitionLostListener.

    Returns the EntryView for the specified key.
    
    Warning:
    
    This method returns a clone of original mapping, modifying the returned value does not change the actual value in the map. One should put modified value back to make changes visible to all nodes.
    
    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.
    
    Parameters:
    
    key - the key of the entry.

    Description copied from interface: IMap
    
    Applies the user defined EntryProcessor to the entry mapped by the key. Returns the the object which is result of the process() method of EntryProcessor.
    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 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.

                                         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

```
    Returns an iterator for iterating the result of the projection on entries in the partitionId which satisfy the predicate.
    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

```
    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 map.
    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 for more details.
    
    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

  - 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 is 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.
