Method Detail

getRegionFactory

public CachingRegionFactory getRegionFactory()

getName

public java.lang.String getName()

Description copied from interface: Region

Retrieve the name of this region.

Specified by:

getName in interface Region

Returns:

The region name

contains

public boolean contains(java.lang.Object key)

Description copied from interface: Region

Determine whether this region contains data for the given key.

The semantic here is whether the cache contains data visible for the current call context. This should be viewed as a "best effort", meaning blocking should be avoid if possible.

Specified by:

contains in interface Region

Parameters:

key - The cache key

Returns:

True if the underlying cache contains corresponding data; false otherwise.

destroy

public void destroy()
             throws CacheException

Description copied from interface: Region

The "end state" contract of the region's lifecycle. Called during SessionFactory.close() to give the region a chance to cleanup.

Specified by:

destroy in interface Region

Throws:

CacheException - Indicates problem shutting down

getSizeInMemory

public long getSizeInMemory()

Description copied from interface: Region

The number of bytes is this cache region currently consuming in memory.

Specified by:

getSizeInMemory in interface Region

Returns:

The number of bytes consumed by this region; -1 if unknown or unsupported.

getElementCountInMemory

public long getElementCountInMemory()

Description copied from interface: Region

The count of entries currently contained in the regions in-memory store.

Specified by:

getElementCountInMemory in interface Region

Returns:

The count of entries in memory; -1 if unknown or unsupported.

getElementCountOnDisk

public long getElementCountOnDisk()

Description copied from interface: Region

The count of entries currently contained in the regions disk store.

Specified by:

getElementCountOnDisk in interface Region

Returns:

The count of entries on disk; -1 if unknown or unsupported.

toMap

public java.util.Map toMap()

Description copied from interface: Region

Get the contents of this region as a map.

Implementors which do not support this notion should simply return an empty map.

Specified by:

toMap in interface Region

Returns:

The content map.

nextTimestamp

public long nextTimestamp()

Description copied from interface: Region

Get the next timestamp according to the underlying cache implementor.

Specified by:

nextTimestamp in interface Region

Returns:

The next timestamp

getTimeout

public int getTimeout()

Description copied from interface: Region

Get a timeout value.

Specified by:

getTimeout in interface Region

Returns:

The time out value

getDataMap

public java.util.Map getDataMap()
