Interface ManagedConnectionResourceListener

public interface ManagedConnectionResourceListener

Listener for the relation between a ManagedConnection and a resource using that ManagedConnection. The resource often needs to know when the ManagedConnection is going to be closed. Similarly the ManagedConnection may need to know when the resource is being closed (so it can free up resources).
