public final class CodePosition
extends Object

This class represent the code position of each instruction during analyse of control flow. Such position are constrained between a min and a max value because it is not possible to know the size of jumps with forward reference

Field Summary

int	max
int	min

Constructor Summary

CodePosition(int min, int max)

Method Summary

void	addOffset(int size) Add a value to min and max fields
boolean	isFix() Returns true if min equals max
void	setPosition(CodePosition pos) Sets the value of this object from an other one
String	toString() Returns a string representation.
