SpatialCondition Class Reference

List of all members.

---

Detailed Description

The FdoSpatialCondition class derives from FdoGeometricCondition and can be used to test whether the value of a geometric property (referenced using the name of the property) and another geometric value satisfy the spatial relationship implied by the operation. Some feature providers may only support literal geometric values; if so, the provider's capabilities will indicate this limitation.

Public Member Functions
__property NAMESPACE_OSGEO_FDO_EXPRESSION::Expression *	get_Geometry ()
	Gets the literal geometric value.
__property NAMESPACE_OSGEO_FDO_FILTER::SpatialOperations	get_Operation ()
	Gets the spatial operation to use.
System::Void	Process (NAMESPACE_OSGEO_FDO_FILTER::IFilterProcessor *processor)
	Overrides FdoFilter.Process to pass the FdoSpatialCondition to the appropriate filter processor operation.
__property System::Void	set_Geometry (NAMESPACE_OSGEO_FDO_EXPRESSION::Expression *value)
	Sets the literal geometric value.
__property System::Void	set_Operation (NAMESPACE_OSGEO_FDO_FILTER::SpatialOperations value)
	Sets the spatial operation to use.
	SpatialCondition (System::IntPtr unmanaged, System::Boolean autoDelete)
	SpatialCondition (NAMESPACE_OSGEO_FDO_EXPRESSION::Identifier *propertyName, NAMESPACE_OSGEO_FDO_FILTER::SpatialOperations operation, NAMESPACE_OSGEO_FDO_EXPRESSION::Expression *geometry)
	Constructs an instance of an FdoSpatialCondition using the specified arguments.
	SpatialCondition (System::String *propertyName, NAMESPACE_OSGEO_FDO_FILTER::SpatialOperations operation, NAMESPACE_OSGEO_FDO_EXPRESSION::Expression *geometry)
	Constructs an instance of an FdoSpatialCondition using the specified arguments.
	SpatialCondition ()
	Constructs a default instance of an FdoSpatialCondition.
