Class CachingPartialFunction<A,​B>

  • All Implemented Interfaces:
    scala.Function1<A,​B>, scala.PartialFunction<A,​B>

    public abstract class CachingPartialFunction<A,​B>
    extends scala.runtime.AbstractPartialFunction<A,​B>

    This is a specialized variant of PartialFunction which is only applicable if you know that isDefinedAt(x) is always called before apply(x)—with the same x of course.

    match(x) will be called for isDefinedAt(x) only, and its semantics are the same as for JavaPartialFunction (apart from the missing because unneeded boolean argument).

    This class is used internal to TestKit and should not be extended by client code directly.
