Interface Updatable

public interface Updatable

Since:

release specific (what release of product did this appear in) Contract by which a Java executable can be delivered updates initiated by user code. This interface is typically used as an optional interface that may be implemented for certain Java classes supplied by the client.

The Updatable interface is supported for the following client classes:

• a Java executable class that implements Executable.

When a job request is updated, Enterprise Scheduler determines if the client class implements the Updatable interface, and if so, calls the onEvent method to notify the client class of the update event.
