CyEvent<Object>

public final class CyShutdownEvent
extends AbstractCyEvent<Object>

An event fired immediately before Cytoscape will be shutdown. This event provides methods for listeners processing this event to abort the shutdown. This event should only be fired synchronously to allow all listeners time to clean up.

Cytoscape Backwards Compatibility (Final Class): This class is final and therefore can't be extended by users. This means that we may add methods for minor version updates. Methods will only be removed for major version updates.
