Interface IntDoubleConsumer

  • 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 IntDoubleConsumer
    Function-Pointer Input: int, double Output: void.

    This is a 'Consumer' with the usual 'accept(...)' method, but actually accepts two primitive-type parameters as follows:

    1. 'int'
    2. 'double'

        void accept​(int i,
            double d)
        Performs this operation on the given arguments.

        FunctionalInterface Target-Method:
        This method corresponds to the @FunctionalInterface Annotation's method requirement. It is the only non-default, non-static method in this interface, and may be the target of a Lambda-Expression or '::' (double-colon) Function-Pointer.
        Parameters:
        i - The integer (first) input-argument.
        d - The double (second) input-argument.

        default IntDoubleConsumer andThen​(IntDoubleConsumer after)
        Returns a composed consumer that performs, in sequence, 'this' operation followed by the after operation. If performing either operation throws an exception, it is relayed to the caller of the composed operation. If performing this operation throws an exception, the 'after' operation will not be performed.
        Parameters:
        after - The operation to perform after this operation
        Returns:
        A composed consumer that performs in sequence 'this' operation followed by the 'after' operation.
        Throws:
        java.lang.NullPointerException - if parameter 'other' is null.
        Code:
        Exact Method Body:
         if (after == null)
     throw new NullPointerException("null has been passed to parameter 'after'");

 return (int i, double d) ->
 {
     this.accept(i, d); 
     after.accept(i, d);
 };
