class PartialFunction

mixin abstract class PartialFunction [ A , B ]
extends java.lang.Object
with (A) => B
with scala.ScalaObject
A partial function of type PartialFunction[A, B] is a unary function where the domain does not include all values of type A. The function isDefinedAt allows to test dynamically, if a value is in the domain of the function.

def isDefinedAt ( x : A ) : scala.Boolean
Checks if a value is contained in the functions domain.
param:
x the value to test
return:
true, iff x is in the domain of this function.
