Interface IntToDoubleFunction

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

    This is a functional interface whose functional method is applyAsDouble(int).
