public final Class BranchHandle

extends InstructionHandle
Class Inheritance
BranchHandle is returned by specialized InstructionList.append() whenever a BranchInstruction is appended. This is useful when the target of this instruction is not known at time of creation and must be set later via setTarget().

Doc from com.sun.org.apache.bcel.internal.generic.InstructionHandle.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.
