Class OpcodeTables

java.lang.Object

org.openjdk.asmtools.jasm.OpcodeTables

public class OpcodeTables
extends Object

OpcodeTables

The OpcodeTables class follows a Singleton Pattern. This class contains Enums, that are contained in private hash maps (lookup tables and reverse lookup tables). These hash maps all have public accessors, which clients use to look-up opcodes.

Tokens in this table carry no external state, and are typically treated as constants. They do not need to be reset.
