Header file: MapBoundary.h.

The AcMapLocationBoundary class is an abstract base class from which all other location boundary classes are derived. Classes derived from the AcMapLocationBoundary class are used to create instances of different types of boundaries. Boundary types include all boundaries, fence, circle, point, polygon, polyline, and window.

A location condition displays objects based on location relative to a specified boundary, represented by an instance of a location boundary subclass. The query can specify whether objects must be completely inside the boundary or cross and have any part inside the boundary.

To use a location boundary in a query, instantiate an object of one of the AcMapLocationBoundary subclasses, associate it with a location condition using the AcMapLocationCondition::SetBoundary function, and add the location condition to a query branch.

Do not subclass from this class.
