Interface EditorContext

All Known Subinterfaces:

InlineContext

All Known Implementing Classes:

BloatContext, CachingBloatContext, PersistentBloatContext

public interface EditorContext

An EditorContext supplies a means of loading and editing classes. Note that a number of these methods are identical to methods in Editor. It is expected that an EditorContext will have a different caching (of ClassEditors, etc.) policy than Editor does. Hence, the methods in EditorContext should be used to edit classes, etc.
