public class IntReference

extends java.lang.Object

Holds a reference to an int. This is useful if you are doing a recursive traversal through a tree structure and want to keep track of which line you are on without using a state variable in the current class. This essentially gives you an int state variable that can be referenced from wherever you are regardless of recursion level.
