Class AbstractEditingPlugin

java.lang.Object
oracle.jdeveloper.java.editing.AbstractEditingPlugin

All Implemented Interfaces:

java.beans.PropertyChangeListener, java.util.EventListener, javax.swing.event.CaretListener, ActionHookInvoker, ActionPostInvoker, CharacterTypedListener, EditorPlugin

public abstract class AbstractEditingPlugin

extends java.lang.Object

implements ActionHookInvoker, ActionPostInvoker, javax.swing.event.CaretListener, CharacterTypedListener, EditorPlugin

The AbstractEditingPlugin is an assistance plugin that helps with Java/JavaScript coding (basically, languages with descendants from C), to take care of the various tedious aspects of editing, such as lining up asterisks in multi-line comments, balancing comment start and ends, and so on.
