Class Location

java.lang.Object
  checkers.flow.Location

public final class Location
extends Object

Represents the location of a Tree. A tree's location may be uniquely identified by its source position (character offset) and Tree.Kind. Source position alone is not sufficient, since many trees may share the same source position (for instance, the member select "a.b" and the identifier "a" in that select have the same source position, but different kinds).
