This class defines the available selection mode types constants when selecting objects.

Whether the object is selected is decided by object, spatial position of selected area and selection mode. When the object is the same with the spatial position of selected area, if the selection mode is different, whether the object is selected also is different. SuperMap supports several select methods, such as selecting by clicking, selecting by drawing a rectangle, selecting by drawing a circle, and etc. The Selection Mode supports all the select methods except the one selecting by clicking.
