* Transactional implementation of {@link BaseMap}.

MapStore Interaction
* When using MapStore, the call to any MapStore method is outside the transactional boundary.
* If you need to have an XATransaction spanning Hazelcast operations and one more other XAResources
* (such as a database), you should not use MapStore. Instead, enlist both resources in a transaction as shown below:
*
*
*
*
* HazelcastInstance client = HazelcastClient.newHazelcastClient();
*
* UserTransactionManager tm = new UserTransactionManager();
* tm.setTransactionTimeout(60);
* tm.begin();
*
* HazelcastXAResource xaResource = client.getXAResource();
* Transaction transaction = tm.getTransaction();
* transaction.enlistResource(xaResource);
*
* // you can enlist more resources here like a database XAResource
* try {
* TransactionContext context = xaResource.getTransactionContext()
* TransactionalMap map = context.getMap("map");
* map.put("key", "value");
* final TransactionalQueue queue = context.getQueue("queue");
* queue.offer("item");
*
* // you can do other resource operations like store/delete to a database
*
* transaction.delistResource(xaResource, XAResource.TMSUCCESS);
* tm.commit();
* } catch (Throwable t) {
* t.printStackTrace();
* transaction.delistResource(xaResource, XAResource.TMFAIL);
* tm.rollback();
* }
