Package org.proforma.variability.util

Class Ribbon<T>

java.lang.Object

org.proforma.variability.util.Ribbon<T>

Type Parameters:

T -

All Implemented Interfaces:

Consumer<T>, Supplier<T>

public class Ribbon<T>
extends Object
implements Supplier<T>, Consumer<T>

A Ribbon connects a data object of type T with a supplier and a consumer. A client of the ribbon can read the data object via the supplier and write or replace the data object via the supplier.

Example:

   java.awt.Point p= new java.awt.Point(4,5);
   Ribbon rx= new Ribbon<>(() -> p.x, newx -> p.x= newx);
 

The previous example allows a client to read and replace the x coordinate of p, without knowing about the type of the whole object p.

The name "ribbon" comes from looking at it as a thing that is start and ending in itself, just like a printer ribbon.
