All Implemented Interfaces:

EDU.purdue.cs.bloat.editor.EditorContext

public class Editor

extends java.lang.Object

implements EDU.purdue.cs.bloat.editor.EditorContext

An Editor is used to edit a number of classes, namely their class information, methods, and fields. Consequently, it manages and delegates a number of its responsibilities to ClassEditor, FieldEditor, and MethodEditor objects.

Various methods are provided to obtain editing objects from reflection objects. When editing is complete, classes, fields, and methods are "committed": changes made to the class/field/method are written back to where they came from.
