org.hibernate.connection: public interface: ConnectionProvider

org.hibernate.connection
public interface: ConnectionProvider [javadoc | source]

All Known Implementing Classes:
DriverManagerConnectionProvider, ProxoolConnectionProvider, UserSuppliedConnectionProvider, DatasourceConnectionProvider, C3P0ConnectionProvider

A strategy for obtaining JDBC connections.

Implementors might also implement connection pooling.

The ConnectionProvider interface is not intended to be exposed to the application. Instead it is used internally by Hibernate to obtain connections.

Implementors should provide a public default constructor.

Method from org.hibernate.connection.ConnectionProvider Summary:
close, closeConnection, configure, getConnection, supportsAggressiveRelease

Method from org.hibernate.connection.ConnectionProvider Detail:
public void close() throws HibernateException Release all resources held by this provider. JavaDoc requires a second sentence.
public void closeConnection(Connection conn) throws SQLException Dispose of a used connection.
public void configure(Properties props) throws HibernateException Initialize the connection provider from given properties.
public Connection getConnection() throws SQLException Grab a connection, with the autocommit mode specified by `hibernate.connection.autocommit`.
public 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. 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.
