class singleton

[source: scala/Seq.scala]

case class singleton[A](val value : A)
extends RandomAccessSeq[A] with Product
Method Summary
override def apply (idx : Int) : A
override def equals (arg0 : Any) : Boolean
override def hashCode : Int
override def isDefinedAt (idx : Int) : Boolean
Is this partial function defined for the index x?
override def length : Int
Returns the length of the sequence.
override final def productArity : Int
return k for a product A(x_1,...,x_k))
override final def productElement (arg0 : Int) : Any
for a case class A(x_1,...,x_k)), returns x_(i+1) for 0 <= i < k
override final 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.
