Header file: MapBoundary.h.

The AcMapBufferFenceBoundary class defines a buffer fence, which is a series of points connected by straight lines, surrounded by a buffer with a specified width.The buffer fence boundary is defined by the coordinates of its points and the width of its buffer. There must be a minimum of two distinct points. If the width of the buffer is 0, the buffer fence boundary is treated as a fence boundary.

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

The AcMapBufferFenceBoundary class is derived from the AcMapFenceBoundary class. To get or set buffer fence boundary points, use the AcMapFenceBoundary::GetPoints or AcMapFenceBoundary::SetPoints function.

Do not subclass from this class.

You create an AcMapBufferFenceBoundary pointer using the new operator and delete allocated memory using the delete operator.
