Pair

public class Pair
extends Object

java.lang.Object
   ↳ android.util.Pair<F, S>


Container to ease passing around a tuple of two objects. This object provides a sensible implementation of equals(), returning true if equals() is true on each of the contained objects.

Summary

Fields

public final F first

public final S second

Public constructors

Pair(F first, S second)

Constructor for a Pair.

Public methods

static <A, B> Pair<A, B> create(A a, B b)

Convenience method for creating an appropriately typed pair.

boolean equals(Object o)

Checks the two objects for equality by delegating to their respective equals(Object) methods.

int hashCode()

Compute a hash code using the hash codes of the underlying objects

String toString()

Returns a string representation of the object.

Inherited methods

From class java.lang.Object

Fields

first

Added in API level 5
F first

second

S second

Public constructors

Pair

Added in API level 5
Pair (F first, 
                S second)

Constructor for a Pair.

Parameters
first F: the first object in the Pair
second S: the second object in the pair

Public methods

create

Added in API level 5
Pair<A, B> create (A a, 
                B b)

Convenience method for creating an appropriately typed pair.

Parameters
a A: the first object in the Pair
b B: the second object in the pair
Returns
Pair<A, B> a Pair that is templatized with the types of a and b

equals

Added in API level 5
boolean equals (Object o)

Checks the two objects for equality by delegating to their respective equals(Object) methods.

Parameters
o Object: the Pair to which this one is to be checked for equality
Returns
boolean true if the underlying objects of the Pair are both considered equal

hashCode

Added in API level 5
int hashCode ()

Compute a hash code using the hash codes of the underlying objects

Returns
int a hashcode of the Pair

toString

Added in API level 5
String toString ()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 

Returns
String a string representation of the object.
