Class ProxyConnection

  • All Implemented Interfaces:
    java.lang.reflect.InvocationHandler

    public class ProxyConnection
    extends JdbcInterceptor
    A ProxyConnection object is the bottom most interceptor that wraps an object of type PooledConnection. The ProxyConnection intercepts three methods:
    • Connection.close() - returns the connection to the pool. May be called multiple times.
    • Object.toString() - returns a custom string for this object
    • PooledConnection.getConnection() - returns the underlying connection
    By default method comparisons is done on a String reference level, unless the PoolConfiguration.setUseEquals(boolean) has been called with a true argument.

      • reset

        public void reset​(ConnectionPool parent,
                          PooledConnection con)
        Description copied from class: JdbcInterceptor
        Gets called each time the connection is borrowed from the pool This means that if an interceptor holds a reference to the connection the interceptor can be reused for another connection.
        This method may be called with null as both arguments when we are closing down the connection.
