Detailed Description

template<size_t D>
class afl::Locator< D >

a helper class to convert a point in space to a hash.

Constructor & Destructor Documentation

template<size_t D> afl::Locator< D >::Locator (  size_t  n, const ddf::Node *  min, const ddf::Node *  max )  [inline]

constructor Parameters: n  the number of points in the array to locate over. This assumes that each side of the hyper-box has n^{1/D}+1 cells along it. min  the minimum point of the bounding box of the space. max  the maximum point of the bounding box of the space.

Member Function Documentation

template<size_t D> size_t afl::Locator< D >::getSide (   )  [inline]

Returns: the number of cells on each side of the hash table

template<size_t D> size_t afl::Locator< D >::locate (  const Point &  x  )  const [inline]

converts a point to a hash so that all points in the same vicinity get close hashes Parameters: x  the point's locations Returns: a hash of the point's location in space

template<size_t D> size_t afl::Locator< D >::locate (  const ddf::Node &  x  )  const [inline]

converts a point to a hash so that all points in the same vicinity get close hashes Parameters: x  the point's locations Returns: a hash of the point's location in space

template<size_t D> std::vector<size_t> afl::Locator< D >::surround (  size_t  x, int  l )  const

gets the surrounding elements to a point, at a distance of l layers Parameters: x  the cell of the point to find the surrounding cells to l  the layer to retreive Returns: a vector of the indices that surround x
