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.

if the locks used by the locking methods of this region are the independent of the cache.
Independent locks are not locked by the cache when the cache is accessed directly. This means that for an independent lock
lock holds taken through a region method will not block direct access to the cache via other means.Copyright © 2001-2013 Red Hat, Inc. All Rights Reserved.
