Description

This class defines a "query." It provides the "key" to the AcDbCompositeFilteredBlockIterator, for which the corresponding index is obtained through the indexClass() method.

The AcDbSpatialFilter::indexClass() method will return AcDbSpatialIndex::desc().

Applications that need to provide their own indexing scheme need to provide versions of these three classes:

• AcDbIndex
• AcDbFilter
• AcDbFilteredBlockIterator
