Interface Function<T,​V>

All Superinterfaces:
Function<T,​V>, 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 Function<T,​V>, 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.
