public abstract class Instruction extends Object
Initially represents a single Java bytecode instruction. Instructions for each bytecode are created when the bytecode is first scanned. Each Instruction will contain a pc (program counter) offset from the beginning of the sequence of bytecode and the length will be determined by the information gleaned from InstructionSet.BYTECODE.
