Detailed Description
template<typename PointT>
class lslgeneric::SpatialIndex< PointT >
Base class for all spatial indexing structures.
A SpatialIndex is anything that holds PointInterface pointers and organizes them in a manner accessible from outside. This class defines what is necessary to be a spatial index - namely the ability to find the cell in which a point is placed and to store newly observed points. It should also be possible to check the size of the occupied space, as well as to get cells neighboring any given cell.
