Constructor Details

GOTO

public GOTO(InstructionHandle target)

Constructs a GOTO instruction.

Parameters:

target - the target instruction.

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, that is, the most specific visitXXX() call comes last.

Specified by:

accept in class Instruction

Parameters:

v - Visitor object.

dump

public void dump(DataOutputStream out)
          throws IOException

Dumps instruction as byte code to stream out.

Overrides:

dump in class BranchInstruction

Parameters:

out - Output stream.

Throws:

IOException - Thrown when an I/O exception of some sort has occurred.

updatePosition

protected int updatePosition(int offset,
 int maxOffset)

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

Parameters:

offset - additional offset caused by preceding (variable length) instructions.

maxOffset - the maximum offset that may be caused by these instructions.

Returns:

additional offset caused by possible change of this instruction's length.
