@FunctionalInterface interface Supplier<R : Any!>
Represents base interface for all functions and function-like objects that return a value and have no arguments. Most of the time this interface is used to pass behaviour to some other code, in many cases enclosing in itself the surrounding state and deferring the computation (creating a clojure).
If you are looking for a supplier interface that can also throw an Exception please use CheckedSupplier instead.
