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 (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
|
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 |
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 |
int hashCode ()
Compute a hash code using the hash codes of the underlying objects
Returns | |
---|---|
int |
a hashcode of the Pair |
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())
