Constructor Detail

LoadInstruction

LoadInstruction(short canon_tag,
               short c_tag)

Empty constructor needed for the Class.newInstance() statement in Instruction.readInstruction(). Not to be used otherwise. tag and length are defined in readInstruction and initFromFile, respectively.

LoadInstruction

protected LoadInstruction(short opcode,
               short c_tag,
               int n)

Parameters:

opcode - Instruction opcode

c_tag - Instruction number for compact version, ALOAD_0, e.g.

n - local variable index (unsigned short)

Method Detail

accept

public void accept(Visitor v)

Call corresponding visitor method(s). The order is: Call visitor methods of implemented interfaces first, then call methods according to the class hierarchy in descending order, i.e., the most specific visitXXX() call comes last.

Specified by:

accept in class Instruction

Parameters:

v - Visitor object
