Member Function Documentation

◆ begin() [1/2]

iterator EE_RTREE::begin ( )
inline

Returns a read/write iterator that points to the first element in the EE_RTREE N.B.

The iteration order of the RTree is not readily apparent and will change if/when you add or move items and the RTree is re-balanced. Any exposure of the RTree contents to the user MUST be sorted before being presented. See SCH_IO_KICAD_SEXPR::Format or SCH_EDITOR_CONTROL::nextMatch for examples.

Returns
Complete RTree of the screen's items

inline

Definition at line 291 of file sch_rtree.h.

References m_tree.

◆ clear()

void EE_RTREE::clear ( )
inline

Remove all items from the RTree.

Referenced by SCH_SCREEN::Clear(), and SCH_SCREEN::FreeDrawList().

◆ contains()

bool EE_RTREE::contains ( const SCH_ITEM aItem,
bool  aRobust = false 
) const
inline

Determine if a given item exists in the tree.

Note that this does not search the full tree so if the item has been moved, this will return false when it should be true.

Parameters
aItemItem that may potentially exist in the tree.
aRobustIf true, search the whole tree, not just the bounding box.
Returns
true if the item definitely exists, false if it does not exist within bbox.

◆ end() [1/2]

◆ remove()

bool EE_RTREE::remove ( SCH_ITEM aItem)
