EdgeEndStar

abstract class EdgeEndStar()

A EdgeEndStar is an ordered list of EdgeEnds around a node. They are maintained in CCW order (starting with the positive x-axis) around the node for efficient lookup and topology building.

protected def insertEdgeEnd(e: EdgeEnd, obj: EdgeEnd): Unit

Insert an EdgeEnd into the map, and clear the edgeList cache, since the list of edges has now changed

def isAreaLabelsConsistent(geomGraph: GeometryGraph): Boolean
def iterator: Iterator[EdgeEnd]

Iterator access to the ordered list of edges is optimized by copying the map collection to a list. (This assumes that once an iterator is requested, it is likely that insertion into the map is complete).
