DistanceCondition Class Reference

Detailed Description

The FdoDistanceCondition class derives from FdoGeometricCondition and can be used to test whether the value of a geometric property is within or beyond a specified distance of the specified geometric value. Some feature providers may only support literal geometric values; if so, the provider's capabilities will indicate this limitation.
