Parameters l:ShutdownHook.Listener the object to call `Listener#onShutdown` on when JGit shuts down Returns:boolean `true` if this object has been registered

public boolean register(ShutdownHook.Listener l)

Register object that needs cleanup during JGit shutdown if it is not already registered. Registration is disabled when JGit shutdown is already in progress.

Parameters

l:ShutdownHook.Listener: the object to call Listener#onShutdown on when JGit shuts down

Returns:boolean

true if this object has been registered

Parameters

l:ShutdownHook.Listener: the object registered to be notified for cleanup when the JVM shuts down

public void onShutdown() Cleanup resources when JGit is shut down. Implementations should be coded defensively they should finish their work quickly they should be written to be thread-safe and to avoid deadlocks insofar as possible they should not rely blindly upon services that may have registered their own shutdown hooks and therefore may themselves be in the process of shutting down attempts to use other thread-based services may lead to deadlocks. See `Runtime#addShutdownHook` for more details.
