  extended by com.android.utils.Pair<S,T>
Type Parameters:
S - The type of the first value
T - The type of the second value

public class Pair<S,T>
extends java.lang.Object

A Pair class is simply a 2-tuple for use in this package. We might want to think about adding something like this to a more central utility place, or replace it by a common tuple class if one exists, or even rewrite the layout classes using this Pair by a more dedicated data structure (so we don't have to pass around generic signatures as is currently done, though at least the construction is helped a bit by the of(S, T) factory method.
