Public Types
typedef VT	Value

Public Member Functions
	SparseGridStorageD (const Ints &counts, const VT &default_value)
GridIndexD< D >	add_voxel (const ExtendedGridIndexD< D > &i, const VT &gi)
	Add a voxel to the storage, this voxel will now have a GridIndex3D.
template<class Functor , class Grid >
Functor	apply (const Grid &g, Functor f) const
bool	get_has_index (const ExtendedGridIndexD< D > &i) const
	Return true if the voxel has been added.
GridIndexD< D >	get_index (const ExtendedGridIndexD< D > &i) const
	requires get_has_index(i) is true.
unsigned int	get_number_of_voxels () const
void	remove_voxel (const GridIndexD< D > &gi)
void	show (std::ostream &out=std::cout) const

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	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.
typedef Data::const_iterator	AllConstIterator
typedef boost::transform_iterator < GetIndex, AllConstIterator >	AllIndexIterator
AllConstIterator	all_begin () const
AllConstIterator	all_end () const
AllIndexIterator	all_indexes_begin () const
AllIndexIterator	all_indexes_end () const

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 \(l_z \leq i_z \leq u_z\).
IndexIterator	indexes_begin (const ExtendedGridIndexD< D > &lb, const ExtendedGridIndexD< D > &ub) const
IndexIterator	indexes_end (const ExtendedGridIndexD< D > &, const ExtendedGridIndexD< D > &) const
base::Vector< GridIndexD< D > >	get_indexes (const ExtendedGridIndexD< D > &lb, const ExtendedGridIndexD< D > &ub) const

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.
