Method Summary

void acceptVisit(com.techtrader.modules.tools.bytecode.visitor.BCVisitor visit)
          Accept a visit from a BCVisitor, calling the appropriate methods to notify the visitor that it has entered this entity, and to provide it with the proper callbacks for each sub-entity owned by this object.

WideInstruction aload()
          Set the type of instruction this wide instruction modifies.

WideInstruction astore()
          Set the type of instruction this wide instruction modifies.

protected void copy(Instruction orig)


WideInstruction dload()
          Set the type of instruction this wide instruction modifies.

WideInstruction dstore()
          Set the type of instruction this wide instruction modifies.

WideInstruction fload()
          Set the type of instruction this wide instruction modifies.

WideInstruction fstore()
          Set the type of instruction this wide instruction modifies.

int getInstruction()
          Get the code of the instruction to modify; this will return one of the constants defined in Constants.

int getLength()
          Return the length in bytes of this opcode, including all arguments.

int getStackChange()
          Return the number of stack positions this instruction pushes or pops during its execution.

WideInstruction iinc()
          Set the type of instruction this wide instruction modifies.

          Set the type of instruction this wide instruction modifies.

WideInstruction lload()
          Set the type of instruction this wide instruction modifies.

WideInstruction lstore()
          Set the type of instruction this wide instruction modifies.

protected void readData(java.io.DataInput in)
          Read the arguments for this opcode from the given stream.

WideInstruction ret()
          Set the type of instruction this wide instruction modifies.

WideInstruction setInstruction(int code)
          Set the code of the instruction to modify.

protected void writeData(java.io.DataOutput out)
