OSGeo::FDO::Filter::SpatialCondition Class Reference

Inherits OSGeo::FDO::Filter::GeometricCondition.

List of all members.

Detailed Description

The SpatialCondition class derives from GeometricCondition 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.
