      • apply

        public E apply​(E input)
        Description copied from interface: Function
        Returns the result of applying this function to input. This method is generally expected, but not absolutely required, to have the following properties:
        • Its execution does not cause any observable side effects.
        • The computation is consistent with equals; that is, Objects.equal(a, b) implies that Objects.equal(function.apply(a), function.apply(b)).
        Specified by:
        apply in interface Function<E,​E>

      • hashCode

        public int hashCode()
        Overrides:
        hashCode in class java.lang.Object

      • equals

        public boolean equals​(java.lang.Object other)
        Description copied from interface: Function
        May return true if is a Function that behaves identically to this function.

        Warning: do not depend on the behavior of this method.

        Historically, Function instances in this library have implemented this method to recognize certain cases where distinct Function instances would in fact behave identically. However, as code migrates to java.util.function, that behavior will disappear. It is best not to depend on it.
