Parameters:

key - the key to the entry.

record - the value to be associated with the specified key.

updateJournal - when true an event is appended to related event-journal

get
```
public Object get(Data key,
                  javax.cache.expiry.ExpiryPolicy expiryPolicy)
```
Description copied from interface: ICacheRecordStore

Gets the value to which the specified key is mapped, or null if this cache contains no mapping for the key.
If the cache is configured to use read-through, and get would return null because the entry is missing from the cache, the Cache's CacheLoader is called in an attempt to load the entry.

Specified by:

get in interface ICacheRecordStore

Parameters:

key - the key whose associated value is to be returned.

expiryPolicy - custom expiry policy or null to use configured default value.

Returns:

Description copied from interface: ICacheRecordStore

Gets a collection of entries from the store, returning them as Map of the values associated with the set of keys requested.
If the cache is configured read-through, and a get for a key would return null because an entry is missing from the cache, the Cache's CacheLoader is called in an attempt to load the entry. If an entry cannot be loaded for a given key, the key will not be present in the returned Map.

Specified by:

Parameters:

keySet - keys whose associated values are to be returned.

expiryPolicy - custom expiry policy or null to use configured default value.

Returns:

A simple wrapper for map of entries that were found for the given keys. Keys not found in the cache are not in the result.

Invokes an EntryProcessor against the Cache.Entry specified by the provided key. If an Cache.Entry does not exist for the specified key, an attempt is made to load it (if a loader is configured) or a surrogate Cache.Entry, consisting of the key with a null value is used instead.

Specified by:

invoke in interface ICacheRecordStore

Parameters:

key - the key of the entry.

entryProcessor - the EntryProcessor to be invoked.

arguments - additional arguments to be passed to the EntryProcessor.

Returns:

the result of the processing, if any, defined by the EntryProcessor implementation.

```

reset
```
public void reset()
```
Description copied from interface: ICacheRecordStore

Specified by:

reset in interface ICacheRecordStore

close
```
public void close(boolean onShutdown)
```
Description copied from interface: ICacheRecordStore
Close is equivalent to below operations in the given order:
- close resources.
- unregister all listeners.
Specified by:

close in interface ICacheRecordStore

Parameters:

onShutdown - true if close is called during CacheService shutdown, false otherwise.

destroyInternals
```
public void destroyInternals()
```
Description copied from interface: ICacheRecordStore

Like ICacheRecordStore.destroy() but does not touch state on other services like event journal service.

Specified by:

destroyInternals in interface ICacheRecordStore

onDestroy
```
protected void onDestroy()
```

closeListeners
```
protected void closeListeners()
```

isWanReplicationEnabled
```
public boolean isWanReplicationEnabled()
```
Description copied from interface: ICacheRecordStore
