00028 /// The IExpressionProcessor interface can be used to process the nodes in an
00029 /// Expression tree. It declares an process operation for each concrete class in
00030 /// the Expression hierarchy. Providers or client applications can create
00031 /// classes that realize this interface to do something meaningful with an
00032 /// Expression hierarchy. For example, an RDBMS feature provider implements a
00033 /// processor class to convert an Expression hierarchy to the SQL equivalent
00034 /// syntax.
