Method Summary
 void close()
          Release all resources held by this provider.
 void closeConnection(Connection conn)
          Dispose of a used connection.
 void configure(Properties props)
          Initialize the connection provider from given properties.
 Connection getConnection()
          Grab a connection, with the autocommit mode specified by hibernate.connection.autocommit.
 boolean supportsAggressiveRelease()
          Does this connection provider support aggressive release of JDBC connections and re-acquistion of those connections (if need be) later?

This is used in conjunction with org.hibernate.cfg.Environment.RELEASE_CONNECTIONS to aggressively release JDBC connections.

public void close()
Description copied from interface: ConnectionProvider
Release all resources held by this provider. JavaDoc requires a second sentence.

supportsAggressiveRelease

public boolean supportsAggressiveRelease()
Description copied from interface: ConnectionProvider
Does this connection provider support aggressive release of JDBC connections and re-acquistion of those connections (if need be) later?

This is used in conjunction with org.hibernate.cfg.Environment.RELEASE_CONNECTIONS to aggressively release JDBC connections. However, the configured ConnectionProvider must support re-acquisition of the same underlying connection for that semantic to work.

Typically, this is only true in managed environments where a container tracks connections by transaction or thread. Note that JTA semantic depends on the fact that the underlying connection provider does support aggressive release.

Specified by:
supportsAggressiveRelease in interface ConnectionProvider

ConnectionProvider.supportsAggressiveRelease()
