  edu.rice.cs.plt.tuple.Tuple
      edu.rice.cs.plt.tuple.Pair<T1,T2>
          edu.rice.cs.plt.tuple.IdentityPair<T1,T2>

All Implemented Interfaces:

java.io.Serializable

public class IdentityPair<T1,T2>
extends Pair<T1,T2>

A pair that defines equals(java.lang.Object) and Tuple.hashCode() in terms of its elements' identity (==) instead of equality (@code equals})

public IdentityPair(T1 first,
                    T2 second)

Method Detail

inverse

public IdentityPair<T2,T1> inverse()

Description copied from class: Pair

Invert a pair. Subclasses should override this method to create a new pair of the same type.

Overrides:

inverse in class Pair<T1,T2>

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class Pair<T1,T2>

Returns:

true iff this is of the same class as o, and each corresponding element is identical (according to ==)

generateHashCode

protected int generateHashCode()

Overrides:

generateHashCode in class Pair<T1,T2>

make

public static <T1,T2> IdentityPair<T1,T2> make(T1 first,
                                               T2 second)

Call the constructor (allows the type arguments to be inferred)

factory

public static <T1,T2> Lambda2<T1,T2,Pair<T1,T2>> factory()

Produce a lambda that invokes the constructor
