@Deprecated(since="1.5.3", forRemoval=true) public class TransactionalMap extends HashMap
Deprecated, for removal: This API element is subject to removal in a future version.
This class (a) isn't exposed in pljava-api, (b) is only used to implement the once-transactional attribute map in Session, and (c) hasn't had transactional behavior even there, since 3ab90e5 (November 2005). Future code needing any kind of store sync'd to PostgreSQL transactions should implement that behavior with Java's ordinary tools, using a TransactionListener to be kept in sync with transactions.
A TransactionalMap acts as a modifiable front for a backing map. All modifications can be reverted by a call to abort or propagated to the backing map by a call to commit. The map is not synchronized so care should be taken if multiple threads will access the map.
