## Interface ToIntQuadFunction<A,B,C,D>

- Type Parameters:
    `A` - the type of the first argument to the function
    `B` - the type of the second argument to the function
    `C` - the type of the third argument to the function
    `D` - the type of the fourth argument to the function
  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 ToIntQuadFunction<A,B,C,D>

  Represents a function that accepts four arguments and produces an int-valued result. This is the `int`-producing primitive specialization for `QuadFunction`.

  This is a functional interface whose functional method is `applyAsInt(Object, Object, Object, Object)`.
