Constructor Details

LoadInstruction

(package private)  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 Details

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.
Overrides:
accept in interface Instruction
Parameters:
v - Visitor object
