Class PersistentBloatContext

java.lang.Object

EDU.purdue.cs.bloat.context.BloatContext

EDU.purdue.cs.bloat.context.PersistentBloatContext

All Implemented Interfaces:

EditorContext, 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.

Constructor Detail

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?

Method Detail

comm

protected static void comm(java.lang.String s)

addClasses

protected void addClasses(java.util.Collection classes)

Adds a bunch of (names of) classes to the hierarchy.

loadClass

                     int[] interfaceIndexes,
                     java.util.List constants)

Description copied from interface: EditorContext

Creates a new ClassInfo

Parameters:
