Class Pair<T1 extends @Nullable Object, T2 extends @Nullable Object>

java.lang.Object
org.plumelib.util.Pair<T1,T2>
Type Parameters:
T1 - the type of the first element of the pair
T2 - the type of the second element of the pair
@Deprecated public class Pair<T1 extends @Nullable Object, T2 extends @Nullable Object> extends Object
Deprecated.
use MPair instead, or IPair for an immutable pair
Mutable pair class: type-safely holds two objects of possibly-different types. Defines toString(), equals(), and hashCode() routines. If you don't need these features, you are better off defining your own tiny class with meaningful field names.
