LayoutVertex class

A vertex represents a Node in a LayoutNetwork, along with its #bounds and #focus and collections of LayoutEdges that come into and go out of the vertex. The #node property may be null for vertexes that represent "dummy" nodes, when the layout wants to work with a network that is not isomorphic with the collection of Nodes and Links being laid out.

This holds layout-specific data for the node. For each kind of layout that uses a LayoutNetwork there is a subclass of LayoutVertex and a subclass of LayoutEdge:

• CircularLayout: CircularVertex and CircularEdge
• ForceDirectedLayout: ForceDirectedVertex and ForceDirectedEdge
• LayeredDigraphLayout: LayeredDigraphVertex and LayeredDigraphEdge
• TreeLayout: TreeVertex and TreeEdge

Modifying a LayoutNetwork or a LayoutVertex or a LayoutEdge does not invalidate the Layout or raise any changed events.

Static Methods

smartComparer(LayoutVertex m, LayoutVertex n) → num

This static function is used to compare the Part#text values of the #nodes of the argument LayoutVertexes. If the text ends in a number, the values are compared as numbers rather than lexicographically. Naturally this comparison is significantly slower than LayoutVertex.standardComparer.

standardComparer(LayoutVertex m, LayoutVertex n) → num

This static function is used to compare the Part#text values of the #nodes of the argument LayoutVertexes. This just does a simple case-sensitive string comparison. Alternatively you may wish to use LayoutVertex.smartComparer or write your own comparison function.
