Parameters:

listener - The notification SshFutureListener - never null

removeCloseFutureListener

public void removeCloseFutureListener(SshFutureListener<CloseFuture> listener)

Description copied from interface: Closeable

Remove a pre-registered close event listener

Parameters:

listener - The register SshFutureListener - never null. Ignored if not registered or resource already closed
