Class TransactionalMap
java.lang.Object
java.util.AbstractMap<K,V>
java.util.HashMap
org.postgresql.pljava.internal.TransactionalMap
- All Implemented Interfaces:
- java.io.Serializable, java.lang.Cloneable, java.util.Map
public class TransactionalMap
- extends java.util.HashMap
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.
