Detailed Description

Class for holding an edge while the underlying graph is being manipulated.

The original FlowBlock nodes that define the end-points of the edge may get collapsed, but the edge may still exist between higher level components. The edge can still be retrieved via the getCurrentEdge() method.

getCurrentEdge()

FlowBlock * FloatingEdge::getCurrentEdge	(	int4 &	outedge,
		FlowBlock *	graph
	)

Get the current form of the edge.

Retrieve the current edge (as a top FlowBlock and the index of the outgoing edge). If the end-points have been collapsed together, this returns NULL. The top and bottom nodes of the edge are updated to FlowBlocks in the current collapsed graph.

Parameters

outedge	will hold the index of the edge (outgoing relative to returned FlowBlock)
graph	is the containing BlockGraph

Returns

the current top of the edge or NULL
