◆ _S_accumulate_node_distance()

_Dist::distance_type KDTree::_S_accumulate_node_distance ( const size_t  __dim,
const _Dist &  __dist,
const _Acc &  __acc,
const _ValA &  __a,
const _ValB &  __b 
)
inline

Compute the distance between two values and accumulate the result for all dimensions.

The distance functor and the accessor are references to the template parameters of the KDTree.

Referenced by KDTree< __K, _Val, _Acc, _Dist, _Cmp, _Alloc >::find_nearest(), and KDTree< __K, _Val, _Acc, _Dist, _Cmp, _Alloc >::find_nearest_if().

◆ _S_node_compare()

bool KDTree::_S_node_compare ( const size_t  __dim,
const _Cmp &  __cmp,
const _Acc &  __acc,
const _ValA &  __a,
const _ValB &  __b 
)
inline

Compare two values on the same dimension using a comparison functor _Cmp and an accessor _Acc.

The comparison functor and the accessor are references to the template parameters of the KDTree.

Referenced by _S_node_descend(), and _S_node_nearest().

◆ _S_node_descend()

const NodeType* KDTree::_S_node_descend ( const size_t  __dim,
const _Cmp &  __cmp,
const _Acc &  __acc,
const _Val &  __val,
const NodeType *  __node 
)
inline

Descend on the left or the right of the node according to the comparison between the node's value and the value.

Note
it's the caller responsibility to check if node is NULL.

◆ _S_node_distance()

_Dist::distance_type KDTree::_S_node_distance ( const size_t  __dim,
const _Dist &  __dist,
const _Acc &  __acc,
const _ValA &  __a,
const _ValB &  __b 
)
inline

Compute the distance between two values for one dimension only.

The distance functor and the accessor are references to the template parameters of the KDTree.

Referenced by _S_node_nearest().

◆ _S_node_nearest()

std::pair<const NodeType*,std::pair<size_t, typename _Dist::distance_type> > KDTree::_S_node_nearest ( const size_t  __k,
size_t  __dim,
SearchVal const &  __val,
const NodeType *  __node,
const _Node_base __end,
const NodeType *  __best,
typename _Dist::distance_type  __max,
const _Cmp &  __cmp,
const _Acc &  __acc,
const _Dist &  __dist,
_Predicate  __p 
)
inline

Find the nearest node to __val from __node

If many nodes are equidistant to __val, the node with the lowest memory address is returned.

Returns
the nearest node of __end node if no nearest node was found for the given arguments.
