Detailed Description

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.
