Interface FigureEnumeration

All Known Implementing Classes:

FigureVectorEnumerator

public interface FigureEnumeration

An object that implements the FigureEnumeration interface generates a series of Figures, one at a time. Successive calls to the nextFigure method return successive Figures of the series. This is just like a standard Enumeration, except we know we are dealing with Figures and therefore users don't have to do any casting.

For example, to print all Figures of a vector v:

     for (FigureEnumeration e = MyFigureEnumerator(v); e.hasMoreElements() ;) {
         System.out.println(e.nextElement());

     }
