Method Detail

apply
public C apply(@Nullable A a)
Description copied from interface:Function
Returns the result of applying this function toinput
. 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 thatObjects.equal(function.apply(a), function.apply(b))
.

equals
public boolean equals(@Nullable java.lang.Object obj)
Description copied from interface:Function
May returntrue
if is aFunction
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 distinctFunction
instances would in fact behave identically. However, as code migrates tojava.util.function
, that behavior will disappear. It is best not to depend on it.
