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.

Public Member Functions

FDO_API double GetDistance ()
 Gets the distance value.
FDO_API FdoExpression * GetGeometry ()
 Gets the literal geometric value.
FDO_API FdoDistanceOperations GetOperation ()
 Gets the distance operation to use.
FDO_API void Process (FdoIFilterProcessor *p)
 Overrides FdoFilter.Process to pass the FdoDistanceCondition to the appropriate filter processor operation.
FDO_API void SetDistance (double value)
 Sets the distance value.
FDO_API void SetGeometry (FdoExpression *value)
 Sets the literal geometric value.
FDO_API void SetOperation (FdoDistanceOperations value)
 Sets the distance operation to use.
FdoString * ToStringInternal (FdoIdentifierCollection *pIdCol)
 This is an internal method. It returns the well defined text representation of the filter.
