public class FilterEngine

extends SupportObject

implements IFilterEngine

One Implementation of a Filter Engine

There are two ways a generic filter engine could run. The first way is to act like a screen, and only let through the data objects that pass the filters that it is put through to the list of targets. This is most similar to optical Filters, which only allow light of certain frequencies to pass through. The second way is to Filter the potential targets based upon the data and only allow the data to pass through to the targets that pass the test. This is most similar to .

This class uses the second method.
