Interface Function<T,V>

All Superinterfaces:

java.util.function.Function<T,V>, java.io.Serializable

All Known Implementing Classes:

CaseFunction, CheckedFunction, DoubleFunctionImpl, Functions.FunctionChain, Functions.SizeFunction, IfFunction, IntegerFunctionImpl, LongFunctionImpl

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface Function<T,V>
extends java.util.function.Function<T,V>, java.io.Serializable

Function is a one-argument lambda which performs a transformation on the object of type T passed to the valueOf() method. This transformation can return the value of calling a getter, or perform some more elaborate logic to calculate a value, of type V.
