`Opcode()`

Method Summary
`static int[]`	`getBranchTargets(byte[] code, int pc, int paddingPC)` Returns an array of branch targets for the instruction.
`static int`	`getInstrSize(byte[] code, int pc)` Return the length of the instruction at the specified offset in the bytecode array.
`static int`	`getInstrSize(byte[] code, int pc, int paddingPC)` Return the length of the instruction at the specified offset in the bytecode array.
`static java.lang.String`	`getOpcodeName(byte opcode)` Return a human-readable version of the code.
`static AInstruction`	`getShortestLoadInstruction(byte baseOpcode, short index)` Return the shortest instruction possible that loads local variable index onto the stack.
`static boolean`	`isBranch(byte opcode)` Return true if the specified code is a branch instruction.
`static boolean`	`isJSR(byte opcode)` Return true if the specified code is a subroutine call.
`static boolean`	`isReturn(byte opcode)` Return true if the specified code is a return instruction.
`static boolean`	`isUnconditionalBranch(byte opcode)` Return true if the specified code is an unconditional branch instruction.
`static byte[]`	`repadInstr(byte[] code, int pc, int paddingPC, int newPC)` Change the padding on the inside of the instruction found at pc, so that it is padded for a PC=newPC, not for a PC=paddingPC.
`static void`	`setBranchTargets(byte[] code, int pc, int[] branchTargets)` Sets the branch targets for an instruction.
