Public Methods

Method Description
Evaluate ( FilterContext context, IFilterTarget target ) : bool

Evaluates the first element in the ContentFilter. If the first or any subsequent element has dependent elements, the dependent elements are evaluated before the root element (recursive descent). Elements which are not linked (directly or indirectly) to the first element will not be evaluated (they have no influence on the result).
