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_SEXPR_PLUGIN::Format or SCH_EDITOR_CONTROL::nextMatch for examples.

Returns

Complete RTree of the screen's items

clear()

void EE_RTREE::clear ( )

inline

Remove all items from the RTree.

 m_tree->RemoveAll();

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

aItem	Item that may potentially exist in the tree.
aRobust	If 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.

Definition at line 125 of file sch_rtree.h.

 BOX2I bbox = aItem->GetBoundingBox();
 
 // Inflate a bit for safety, selection shadows, etc.

 const int mmin[3] = { type, bbox.GetX(), bbox.GetY() };
