Method Detail

acceptback to summary
public void accept(final Visitor v)

Implements abstract org.apache.bcel.generic.Instruction.accept.

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.

Parameters
v:Visitor

Visitor object

public void dump(final DataOutputStream out) throws IOException

Overrides org.apache.bcel.generic.BranchInstruction.dump.

Dump instruction as byte code to stream out.

Parameters
out:DataOutputStream

Output stream

Exceptions
IOException:

Doc from org.apache.bcel.generic.Instruction.dump.

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

updatePositionback to summary
protected int updatePosition(final int offset, final int maxOffset)

Overrides org.apache.bcel.generic.BranchInstruction.updatePosition.

Doc from org.apache.bcel.generic.BranchInstruction.updatePosition.

Called by InstructionList.setPositions when setting the position for every instruction. In the presence of variable length instructions 'setPositions' performs multiple passes over the instruction list to calculate the correct (byte) positions and offsets by calling this function.

Parameters
offset:int

additional offset caused by preceding (variable length) instructions

maxOffset:int

the maximum offset that may be caused by these instructions

Returns:int

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