Method Detail

isTransactionAware

public boolean isTransactionAware()

Specified by:

isTransactionAware in interface org.hibernate.cache.TransactionalDataRegion

getCacheDataDescription

public org.hibernate.cache.CacheDataDescription getCacheDataDescription()

Specified by:

Specified by:

buildAccessStrategy in interface org.hibernate.cache.EntityRegion

Throws:

org.hibernate.cache.CacheException

isRegisterInterestRequired

public boolean isRegisterInterestRequired()

Should this region should register interest in keys.

Returns:

true for client regions with storage

registerInterest

public void registerInterest(java.lang.Object key)

register interest in this key, if not already registered

Parameters:

key -

registerInterest

public void registerInterest(java.util.Collection<?> list)

getAll

public void getAll(java.util.Collection<?> keys)

wraps the keys in KeyWrapper and calls getAll on the underlying GemFire region. When the underlying region is a proxy region, the fetched entries are stored in a local map.

Parameters:

keys -

get

If this key was pre-fetched, get the entity.

Parameters:

key -
