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.

GetEnumerator()

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).

Declaration

public IEnumerator<EdgeEnd> GetEnumerator()

Returns

Type	Description
IEnumerator<EdgeEnd>	Access to ordered list of edges.
