FDO API Reference Feature Data Objects

BEGIN_NAMESPACE_OSGEO_FDO_EXPRESSION public __gc __interface IExpressionProcessor
 

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