Throws:

Exception

connectionClosed

void connectionClosed(SessionProtocol protocol, InetSocketAddress remoteAddr, InetSocketAddress localAddr, AttributeMap attrs) throws Exception

Invoked when a connection in the connection pool has been closed.

Throws:

Exception

unwrap

default ConnectionPoolListener unwrap()

Description copied from interface: Unwrappable

Unwraps this object and returns the object being decorated. If this Unwrappable is the innermost object, this method returns itself. For example:

 class Foo implements Unwrappable {}

 class Bar<T extends Unwrappable> extends AbstractUnwrappable<T> {
     Bar(T delegate) {
         super(delegate);
     }
 }

 class Qux<T extends Unwrappable> extends AbstractUnwrappable<T> {
     Qux(T delegate) {
         super(delegate);
     }
 }

 Foo foo = new Foo();
 assert foo.unwrap() == foo;

 Bar<Foo> bar = new Bar<>(foo);
 assert bar.unwrap() == foo;

 Qux<Bar<Foo>> qux = new Qux<>(bar);
 assert qux.unwrap() == bar;
 assert qux.unwrap().unwrap() == foo;
