Package Torello.Java.Function

Interface IntIntCharCons

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 IntIntCharCons

Function-Pointer Input: int, int, char Output: void.

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

1. 'int'
2. 'int'
3. 'char'

Method Detail

accept

🡇 ⇈ ⮫ 🗕 🗗 🗖

void accept(int i1,
            int i2,
            char c)

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:

i1 - The first integer-parameter.

i2 - The second integer-parameter.

c - A 'char' parameter.

andThen

default IntIntCharCons andThen(IntIntCharCons 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 - This throws if null is passed to 'after'.

Code:

Exact Method Body:

 if (after == null) throw new NullPointerException
     ("null has been passed to parameter 'after'");

 return (int i1, int i2, char c) ->
 {
     this.accept(i1, i2, c);
     after.accept(i1, i2, c);
 };
