public boolean isTransactionAware()

Is the underlying cache implementation aware of (and "participating in") ongoing JTA transactions?

Regions which report that they are transaction-aware are considered "synchronous", in that we assume we can immediately (i.e. synchronously) write the changes to the cache and that the cache will properly manage application of the written changes within the bounds of ongoing JTA transactions. Conversely, regions reporting false are considered "asynchronous", where it is assumed that changes must be manually delayed by Hibernate until we are certain that the current transaction is successful (i.e. maintaining READ_COMMITTED isolation).

Returns:boolean

True if transaction aware; false otherwise.
