Interface DoubleToLongFunction

  • 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 DoubleToLongFunction
    Represents a function that accepts a double-valued argument and produces a long-valued result. This is the double-to-long primitive specialization for Function.

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