Package io.virtdata.functionadapters

Class ToLongFunction

  • All Implemented Interfaces:
    java.util.function.LongFunction<java.lang.Object>
    public class ToLongFunction
extends java.lang.Object
implements java.util.function.LongFunction<java.lang.Object>
    Adapts any compatible FunctionalInterface type to a LongFunction, for use with higher-order functions, when they require a LongFunction as an argument. Some of the higher-order functions within this library specifically require a LongFunction as an argument, while some of the other functions are provided in semantically equivalent forms with compatible types which can't be converted directly or automatically by Java. In such cases, those types of functions can be wrapped with the forms described here in order to allow the inner and outer functions to work together.
