Class DeleteHandlerService

java.lang.Object
  oracle.ide.navigator.DeleteHandlerService

public final class DeleteHandlerService
extends java.lang.Object

A service for registering DeleteActionHandlers for a specific subtype Node. Once a delete action handler is registered for a subtype of Node, the IDE will invoke the handler whenever a node of that type is to be deleted, using any of the possible gestures, once the node in the navigator and selecting Delete:

• Right-clicking
• Pressing the delete key once the node is selected in the navigator
• File->Delete
• Edit->Delete

The way a subtype of Node is registered with the service is DeleteHandlerService.registerDeleteActionHandler(MyCompexNode.class, MyComplexNodeDeleteHandler.class); The way to manually invoke the delete handler for a node is to call DeleteHandlerService.createDeleteHandler(context) where the context has its selection set to an array of the node subtypes.
