Member Function Documentation

Insert()

template<class T >

void CN_RTREE< T >::Insert ( T  aItem )

inline

Function Insert() Inserts an item into the tree.

Item's bounding box is taken via its BBox() method.

Query()

template<class T >

template<class Visitor >

void CN_RTREE< T >::Query ( const BOX2I &  aBounds, const LAYER_RANGE &  aRange, Visitor &  aVisitor  ) const

inline

Function Query() Executes a function object aVisitor for each item whose bounding box intersects with aBounds.

Remove()

template<class T >

void CN_RTREE< T >::Remove ( T  aItem )

inline

Function Remove() Removes an item from the tree.

Removal is done by comparing pointers, attempting to remove a copy of the item will fail.

RemoveAll()

template<class T >

void CN_RTREE< T >::RemoveAll ( )

inline

Function RemoveAll() Removes all items from the RTree.
