Public Attributes | |
union { | |
struct leaf { | |
IndexType left | |
IndexType right | |
Indices of points in leaf node. | |
} lr | |
struct nonleaf { | |
int divfeat | |
Dimension used for subdivision. | |
DistanceType divlow | |
DistanceType divhigh | |
The values used for subdivision. | |
} sub | |
} | node_type |
Node * | child1 |
Node * | child2 |
Child nodes (both=NULL mean its a leaf node) | |
union { ... } nanoflann::KDTreeBaseClass< Derived, Distance, DatasetAdaptor, DIM, IndexType >::Node::node_type |
Union used because a node can be either a LEAF node or a non-leaf node, so both data fields are never used simultaneously
