Header file: MapBoundary.h.

The AcMapFenceBoundary class defines a fence, which is a series of points connected by straight lines. The fence boundary is defined by the coordinates of its points. There must be a minimum of two distinct points.

A query built on a fence boundary can select all drawing objects that cross the fence boundary.

The AcMapFenceBoundary class is derived from the AcMapLocationBoundary class.

The AcMapBufferFenceBoundary, AcMapPolygonBoundary, and AcMapWindowBoundary classes are derived from the AcMapFenceBoundary class.

Do not subclass from this class.

You get an AcMapFenceBoundary pointer using the new operator, so you are responsible for deleting allocated memory with the delete operator.
