The connection * can be recycled rather than being closed when an application is * finished with it, thus reducing the number of connections that * need to be made. * <P> * An application programmer does not use the <code>PooledConnection</code> * interface directly; rather, it is used by a middle tier infrastructure * that manages the pooling of connections. * <P> * When an application calls the method <code>DataSource.getConnection</code>, * it gets back a <code>Connection</code> object. If connection pooling is * being done, that <code>Connection</code> object is actually a handle to * a <code>PooledConnection</code> object, which is a physical connection. * <P> * The connection pool manager, typically the application server, maintains * a pool of <code>PooledConnection</code> objects. If there is a * <code>PooledConnection</code> object available in the pool, the * connection pool manager returns a <code>Connection</code> object that * is a handle to that physical connection. * If no <code>PooledConnection</code> object is available, the * connection pool manager calls the <code>ConnectionPoolDataSource</code> * method <code>getPoolConnection</code> to create a new physical connection. The * JDBC driver implementing <code>ConnectionPoolDataSource</code> creates a * new <code>PooledConnection</code> object and returns a handle to it. * <P> * When an application closes a connection, it calls the <code>Connection</code> * method <code>close</code>. When connection pooling is being done, * the connection pool manager is notified because it has registered itself as * a <code>ConnectionEventListener</code> object using the * <code>ConnectionPool</code> method <code>addConnectionEventListener</code>. * The connection pool manager deactivates the handle to * the <code>PooledConnection</code> object and returns the * <code>PooledConnection</code> object to the pool of connections so that * it can be used again. Thus, when an application closes its connection, * the underlying physical connection is recycled rather than being closed. * <P> * The physical connection is not closed until the connection pool manager * calls the <code>PooledConnection</code> method <code>close</code>. * This method is generally called to have an orderly shutdown of the server or * if a fatal error has made the connection unusable. * * <p> * A connection pool manager is often also a statement pool manager, maintaining * a pool of <code>PreparedStatement</code> objects. * When an application closes a prepared statement, it calls the * <code>PreparedStatement</code> * method <code>close</code>. When <code>Statement</code> pooling is being done, * the pool manager is notified because it has registered itself as * a <code>StatementEventListener</code> object using the * <code>ConnectionPool</code> method <code>addStatementEventListener</code>. * Thus, when an application closes its <code>PreparedStatement</code>, * the underlying prepared statement is recycled rather than being closed. * <P> * * @since 1.4 */ public interface PooledConnection { /** * Creates and returns a <code>Connection</code> object that is a handle * for the physical connection that * this <code>PooledConnection</code> object represents. * The connection pool manager calls this method when an application has * called the method <code>DataSource.getConnection</code> and there are * no <code>PooledConnection</code> objects available.
