Method Detail

instantiateBackingMap

public Map instantiateBackingMap(String sName)

Instantiate a [thread safe] Map that should be used by a CacheService to store cached values for a NamedCache with the specified name.

If the contents of the Map can be modified by anything other than the CacheService itself (e.g. if the Map automatically expires its entries periodically or size-limits its contents), then the returned object must implement the ObservableMap interface.

Parameters:

sName - the name of the NamedCache for which this backing map is being created

Returns:

an object implementing the Map interface that will provide backing storage for the specified cache name

isBackingMapPersistent

public boolean isBackingMapPersistent(String sName)

Determine if the contents of the Map that is used by a CacheService to store cached values for a NamedCache with the specified name should be persisted.

Parameters:

sName - the name of the NamedCache

Returns:

true if the CacheService should persist the backing storage of the specified NamedCache

isBackingMapSlidingExpiry

public boolean isBackingMapSlidingExpiry(String sName)

Determine if the Map that is used by a CacheService to store cached values for a NamedCache with specified name enables the sliding expiry - the expiry delay being extended by the read operations.

Parameters:

sName - the name of the NamedCache

Returns:

true if the backing map of the specified NamedCache enables the sliding expiry

getStorageAccessAuthorizer

public StorageAccessAuthorizer getStorageAccessAuthorizer(String sName)

Determine the StorageAccessAuthorizer that is used by a CacheService to secure access to the NamedCache with the specified name.

Parameters:

sName - the name of the NamedCache

Returns:

the StorageAccessAuthorizer or null if the authorizer is not configured

releaseBackingMap

public void releaseBackingMap(String sName,
                              Map map)

Release the specified Map that was created using the BackingMapManager.instantiateBackingMap(String) method. This method is invoked by the CacheService when the CacheService no longer requires the specified Map object.

Specified by:

releaseBackingMap in interface BackingMapManager

Overrides:

releaseBackingMap in class AbstractBackingMapManager

Parameters:

sName - the name of the NamedCache for which the specified Map object has acted as the backing map

map - the Map object that is being released

getCacheFactory

public DefaultConfigurableCacheFactory getCacheFactory()

Obtain the "container" DefaultConfigurableCacheFactory that created this manager and which this manager is bound to.

Returns:

the DefaultConfigurableCacheFactory that created this manager
