public abstract class Attribute

extends BCEntity

implements Constants, com.techtrader.modules.tools.bytecode.visitor.VisitAcceptor

Representation of an attribute in a .class file. Attributes are used to represent constants and the code of methods, among other things. All attributes contain at a minimum a name, which is immutable, as it determines the attribute's type.
