Class CachingBloatContext

java.lang.Object

EDU.purdue.cs.bloat.context.BloatContext

EDU.purdue.cs.bloat.context.PersistentBloatContext

EDU.purdue.cs.bloat.context.CachingBloatContext

All Implemented Interfaces:

EditorContext, EDU.purdue.cs.bloat.inline.InlineContext

public class CachingBloatContext
extends PersistentBloatContext

Does a lot of the same stuff as PersistentBloatContext except that it manages the chaches of BLOAT objects. For example, when a MethodEditor is no longer needed, it is removed from the cache if it is not dirty. This context is meant to used in volatile memory.
