Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals( Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Public Constructors

public Pair (F first, S second)

Added in API level 5

Constructor for a Pair.

Parameters

first	the first object in the Pair
second	the second object in the pair

Public Methods

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

Added in API level 5

Convenience method for creating an appropriately typed pair.

Parameters

a	the first object in the Pair
b	the second object in the pair

Returns

public boolean equals (Object o)

Added in API level 5

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

Parameters

o	the `Pair` to which this one is to be checked for equality

Returns

true if the underlying objects of the Pair are both considered equal

public int hashCode ()

Added in API level 5

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

Returns

a hashcode of the Pair
