+ Inheritance diagram for IMP::algebra::SparseGridStorageD< D, VT, Base, Map >:

Detailed Description

template<int D, class VT, class Base, class Map = typename boost::unordered_map<GridIndexD<D>, VT>>
class IMP::algebra::SparseGridStorageD< D, VT, Base, Map >

Store a grid as a sparse set of voxels (only the voxels which have been added are actually stored). The get_has_index() functions allow one to tell if a voxel has been added.

Warning: SparseGridStorageD has not been stabilized and is likely to change without notice.

Base should be one of BoundedGridRangeD or UnboundedGridRangeD.

Operator []

Operator[] isn't very useful at the moment as it can only be used with a cell which has already been set. This behavior/the existence of these functions is likely to change.

const VT at (GridIndexD< D >) const
 
VT & at (GridIndexD< D >)
 
const VT operator[] (GridIndexD< D >) const
 
VT & operator[] (GridIndexD< D >)
 

Iterators through set cells

Iterate through the voxels which have been set. The value type is a pair of GridIndex3D and VT.

Index Iterators

Iterate through a range of actual indexes. The value type for the iterator is an GridIndex3D.

The range is defined by a pair of indexes. It includes all indexes in the axis aligned box defined by lb as the lower corner and the second as the ub. That is, if lb is \((l_x, l_y, l_z)\) and ub is \((u_x, u_y, u_z)\), then the range includes all indexes \((i_x, i_y, i_z)\) such that \(l_x \leq i_x \leq u_x\), \(l_y \leq i_y \leq u_y\) and \(l_z \leq i_z \leq u_z\).
