Package EDU.purdue.cs.bloat.context

Class PersistentBloatContext

  • All Implemented Interfaces:
    EditorContext, EDU.purdue.cs.bloat.inline.InlineContext
    Direct Known Subclasses:
    CachingBloatContext
    public class PersistentBloatContext
extends BloatContext
    Maintains all BLOAT data structures as if they were meant to reside in a persistent store. As a result, it keeps every piece of BLOAT data around because it might be needed in the future. No fancing cache maintainence is performed. Because we are going for maximum information we take the closure of classes when working with the class hierarchy.

      • PersistentBloatContext

        public PersistentBloatContext​(ClassInfoLoader loader)
        Constructor. Each BloatContext stems from a ClassInfoLoader. Using the loader it can create an Editor and such. Initially, no classes are loaded.

      • PersistentBloatContext

        protected PersistentBloatContext​(ClassInfoLoader loader,
                                 boolean closure)
        Constructor. It is the responsibility of the subclasses to add classes to the hierarchy by calling addClasses.
        Parameters:
        loader - Used to load classes
        closure - Do we look for the maximum number of classes?
