/// \brief
/// The IFilterProcessor interface can be used to process the nodes in a filter
/// tree. It declares a process operation for each concrete class in the filter
/// hierarchy. Providers or client applications can create classes that realize
/// this interface to do something meaningful with a filter hierarchy. For
/// example, a RDBMS feature provider can implement a processor class to convert a
/// filter hierarchy to the SQL equivalent syntax.
