class Tuple2
[source: scala/Tuple2.scala]
case class Tuple2[+T1, +T2](val _1 : T1, val _2 : T2)
extends Product2[T1, T2]
Tuple2 is the canonical representation of a @see Product2
Method Summary
override def canEqual (arg0 : Any) : Boolean
A method that should be called from every well-designed equals method that is open to be overridden in a subclass. See Programming in Scala, Chapter 28 for discussion and design.
override def equals (arg0 : Any) : Boolean
The equality method defined in `AnyRef`.
override def hashCode : Int
Returns a hash code value for the object.
override def productPrefix : java.lang.String
By default the empty string. Implementations may override this method in order to prepend a string prefix to the result of the toString methods.
def swap : (T2, T1)
Swap the elements of the tuple
override def toString : java.lang.String
Returns a string representation of the object.

Method Details
override def toString : java.lang.String
Returns a string representation of the object.

The default representation is platform dependent.

Returns
a string representation of the object.

def swap : (T2, T1)
Swap the elements of the tuple
def zip[Repr1, El1, El2, To](implicit w1 : <:<[T1, TraversableLike[El1, Repr1]], implicit w2 : <:<[T2, Iterable[El2]], implicit cbf1 : CanBuildFrom[Repr1, (El1, El2), To]) : To
def zipped[Repr1, El1, Repr2, El2](implicit w1 : <:<[T1, TraversableLike[El1, Repr1]], implicit w2 : <:<[T2, IterableLike[El2, Repr2]]) : Zipped[Repr1, El1, Repr2, El2]
override def hashCode : Int
Returns a hash code value for the object.

The default hashing algorithm is platform dependent. Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)) yet not be equal (o1.equals(o2) returns false). A degenerate implementation could always return 0. However, it is required that if two objects are equal (o1.equals(o2) returns true) that they have identical hash codes (o1.hashCode.equals(o2.hashCode)). Therefore, when overriding this method, be sure to verify that the behavior is consistent with the equals method.

Returns
the hash code value for the object.
