addCloseFutureListener

public void addCloseFutureListener(SshFutureListener<CloseFuture> listener)

Description copied from interface: Closeable

Pre-register a listener to be informed when resource is closed. If resource is already closed, the listener will be invoked immediately and not registered for future notification

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

Description copied from interface: Closeable

Close this resource asynchronously and return a future. Resources support two closing modes: a graceful mode which will cleanly close the resource and an immediate mode which will close the resources abruptly.

Parameters:

immediately - true if the resource should be shut down abruptly, false for a graceful close

Returns:

a CloseFuture representing the close request
