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

Definition at line 291 of file sch_rtree.h.

◆ clear()

void EE_RTREE::clear ( )

inline

Remove all items from the RTree.

◆ 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.
