Parameters:

opcode - instruction opcode

o - referred to in constant pool

Method Detail

dump

public void dump(DataOutputStream out)
          throws IOException

Dump instruction as byte code to stream out.

Overrides:

dump in class Bytecodes.Instruction

Parameters:

out - Output stream

Throws:

IOException

toString

public String toString(boolean verbose)

Long output format: <name of opcode> "["<opcode number>"]" "("<length of instruction>")" "<"< constant pool index>">"

Overrides:

toString in class Bytecodes.Instruction

Parameters:

verbose - long/short format switch

Returns:

mnemonic for instruction

toString

                            jwutil.io.ByteSequence bytes,
                            boolean wide)
                     throws IOException

Read needed data (i.e., index) from file.

Overrides:

initFromFile in class Bytecodes.Instruction

Parameters:

bytes - input stream

wide - wide prefix?
