HTM SpatialIndex Class Reference

class SpatialDomain

A spatial domain is a list of spatial convexes

Public Fields

const SpatialIndex*	index
static uint64	topBit_ The vector of convexes

Public Methods

	SpatialDomain (const SpatialIndex * idx = 0) Constructor
	~SpatialDomain () Destructor
void	setIndex (const SpatialIndex *) Set index pointer
void	add (SpatialConvex &) Add a convex
void	simplify () Simplify the Domain, remove redundancies
bool	intersect (const SpatialIndex * idx, BitList & partial, BitList & full) Intersect with index
bool	intersect (const SpatialIndex * idx, ValVec & partial, ValVec & full) Same intersection, but return vectors of ids instead of bitlists.
bool	intersect (const SpatialIndex * idx, ValVec & idlist) Same intersection, but return just a list of IDs not level depth
size_t	numConvexes () numConvexes: give back the number of convexes
SpatialConvex&	operator [] (size_t i) [] operator: give back convex
void	read (istream&) read from stream
void	write (ostream&) const write to stream
static void	ignoreCrLf (istream &) A pointer to the index

Same intersection, but return vectors of ids instead of bitlists.

bool intersect(const SpatialIndex * idx, ValVec & idlist)

Same intersection, but return just a list of IDs not level depth

size_t numConvexes()

numConvexes: give back the number of convexes

SpatialConvex& operator [](size_t i)

[] operator: give back convex

void read(istream&)

read from stream

void write(ostream&) const

write to stream

const SpatialIndex* index
