public final Class Mod

extends Object
Class Inheritance
This class defines constants and convenience methods for the handling of modifiers as defined by the JVM.

Notice: This class should be named IClass.IModifier, but changing the name would break existing client code. Thus it won't be renamed until there's a really good reason to do it (maybe with a major design change).
