Interface ContextShutdownWatcher

All Known Implementing Classes:

ZMQSendTester

public interface ContextShutdownWatcher

Interface implemented by objects that wish to be notified when their containing context is about to be shutdown.

When the last user leaves a context and there are no objects retaining the context to keep it open, the server shuts the context down. Any modified state associated with the context or any of the objects contained by it is written to persistent storage and the context and its attendent objects become eligible for garbage collection. Prior to doing this, however, the server first calls the noteContextShutdown() method of each object implementing this interface that has registered an interest by called the context's registerContextShutdownWatcher() method.

Instances of subclasses of Mod that implement this interface are automatically registered when they are attached to the context or to an object contained by the context.
