6.2 Using rwsf::Enumeration

A rwsf::Enumeration object provides a simple, safe interface to a collection of objects. HydraExpress returns an instance of rwsf::Enumeration to represent a list of items. For simplicity, an enumeration provides only two functions: the hasMoreElements() function which returns true if the enumeration contains another element; and the nextElement() function which returns the next object in the enumeration. An enumeration is designed for code such as the loop below:

The nextElement() function throws rwsf::OutOfBoundsError if the enumeration has no more elements.
