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.

Pair
public 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
public static 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
public boolean equals (Object o)
Checks the two objects for equality by delegating to their respective
Object#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
public int hashCode ()
Compute a hash code using the hash codes of the underlying objects
| Returns | |
|---|---|
int |
a hashcode of the Pair |
toString
public 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. |
