Class MZFCompressor

java.lang.Object
  harpoon.Analysis.SizeOpt.MZFCompressor

public class MZFCompressor
extends Object

The MZFCompressor class implements a class transformation aimed at eliminating "mostly-zero" (or "mostly (any constant)") fields from classes (thus reducing memory consumption). Each class is transformed into several, each with one additional field added. Thus we only need allocate fields that this particular instance will actually use.
