All Implemented Interfaces:

Cloneable, InstructionTargeter

Direct Known Subclasses:

LineNumberTag, LocalVariableTag

public abstract class Tag
extends Object
implements InstructionTargeter, Cloneable

A tag is an instruction-targeter that does not remember its target. Instruction handles will maintain a list of targeters but there won't be a way to get back from the tag to the instruction. Maintaining these backward/forward links just slows everything down.
