Class AmbiguateProperties

  • All Implemented Interfaces:
    CompilerPass
    public class AmbiguateProperties
extends java.lang.Object
implements CompilerPass
    Renames unrelated properties to the same name, using type information. This allows better compression as more properties can be given short names.

    Properties are considered unrelated if they are never referenced from the same type or from a subtype of each others' types, thus this pass is only effective if type checking is enabled.

    Example: Foo.fooprop = 0; Foo.fooprop2 = 0; Bar.barprop = 0; becomes: Foo.a = 0; Foo.b = 0; Bar.a = 0;
