template struct mrpt::math::KDTreeCapable::TKDTreeDataHolder

Internal structure with the KD-tree representation (mainly used to avoid copying pointers with the = operator)

template <int _DIM = -1>
struct TKDTreeDataHolder
{
    // typedefs

    typedef nanoflann::KDTreeSingleIndexAdaptor<metric_t, Derived, _DIM, std::size_t> kdtree_index_t;

fields

    std::unique_ptr<kdtree_index_t> index;

    size_t m_num_points = 0;

    // construction

    TKDTreeDataHolder(const TKDTreeDataHolder&);

    //
methods

    TKDTreeDataHolder& operator = (const TKDTreeDataHolder& o);

Fields

std::unique_ptr<kdtree_index_t> index

nullptr or the up-to-date index

size_t m_dim = _DIM

Dimensionality.

typ: 2,3

Construction

TKDTreeDataHolder(const TKDTreeDataHolder&)

Copy constructor: It actually does NOT copy the kd-tree, a new object will be created if required!

Methods

TKDTreeDataHolder& operator = (const TKDTreeDataHolder& o)

Copy operator: It actually does NOT copy the kd-tree, a new object will be created if required!

void clear()
