java.lang.Object

jfun.jaskell.function.Function1

jfun.jaskell.function.Function4

jfun.jaskell.StrictFunction4

All Implemented Interfaces:

java.io.Serializable, Function

public abstract class StrictFunction4
extends Function4

extend this class to provide a strict function implementation. Subclassing this class is more efficient than calling addStrictFunction.
A strict function is a function whose arguments are evaluated before the function body is evaluated.
