Constructor Detail

GOTO

public GOTO(InstructionHandle target)
Method Detail

dump

public void dump(java.io.DataOutputStream out)
          throws java.io.IOException
Dump instruction as byte code to stream out.
Overrides:
dump in class BranchInstruction
Parameters:
out - Output stream

updatePosition

protected int updatePosition(int offset,
                             int max_offset)
Called in pass 2 of InstructionList.setPositions() in order to update the branch target, that may shift due to variable length instructions.
Overrides:
updatePosition in class BranchInstruction
Following copied from class: org.apache.bcel.generic.BranchInstruction
Parameters:
offset - additional offset caused by preceding (variable length) instructions
max_offset - the maximum offset that may be caused by these instructions
Returns:
additional offset caused by possible change of this instruction's length

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 class Instruction
Parameters:
v - Visitor object
