public class TLcdOGCBBoxOperator
extends TLcdDataObject
implements ILcdOGCCondition

This class represents the element <ogc:BBOX>.

According to the OGC Filter specification, it provides a more compact way of encoding the very common bounding box constraint based on the gml:Envelope geometry. It is equivalent to the spatial operation

 <Not>
   <Disjoint>...</Disjoint>
 </Not>
 

meaning that the <BBOX> operator should identify all geometries that spatially interact with the box.

A TLcdOGCBBoxOperator instance is composed of a TLcdOGCPropertyName instance that identifies the geometric property to be considered for the intersection, an ILcdBounds instance that indicates the envelope to intersect with and a ILcdGeoReference that indicates the spatial reference of the given envelope in case the envelope doesn't contain one.
