This class implements the EvaluatorFactory interface. This factory can produce evaluators that can answer true or false to a user meeting any logical combination of attribute values in the passed in IPerson object. It does so be defining one test element, <attribute>, and a logical grouping element, <paren>, that behaves according to a set mode. The <dlm:audience> element using this factory must contain at least one and may contain many of these elements in any combination.
Syntactic Configuration Elements
<paren> ELEMENT
Like the <dlm:audience> element this element must contain at least one and may contain many <attribute> or <parent> elements. In fact the implementing class implements the Evaluator interface enabling the implementing class to be passed back from the factory.
