Interface ThrowableToLongFunction<T>

  • Type Parameters:
    T - the type of the input to the function
    All Superinterfaces:
    java.util.function.ToLongFunction<T>
    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 ThrowableToLongFunction<T>
    extends java.util.function.ToLongFunction<T>
    Represents a function that produces a long-valued result. This is the long-producing primitive specialization for Function.

    Permits checked exceptions unlike ToLongFunction

    This is a functional interface whose functional method is applyAsLong(Object).
