Class PGObjectFactory

java.lang.Object
  org.postgresql.ds.common.PGObjectFactory

All Implemented Interfaces:

javax.naming.spi.ObjectFactory

Direct Known Subclasses:

PGXADataSourceFactory

public class PGObjectFactory
extends java.lang.Object
implements javax.naming.spi.ObjectFactory

Returns a DataSource-ish thing based on a JNDI reference. In the case of a SimpleDataSource or ConnectionPool, a new instance is created each time, as there is no connection state to maintain. In the case of a PoolingDataSource, the same DataSource will be returned for every invocation within the same VM/ClassLoader, so that the state of the connections in the pool will be consistent.
