void	assignPorts(LayoutGraph graph, ILayers layers, ILayoutDataProvider ldp, IItemFactory itemFactory) Assigns to each edge of the graph a source port and target port coordinate pair.

Method Detail

assignPorts

void assignPorts(LayoutGraph graph,
                 ILayers layers,
                 ILayoutDataProvider ldp,
                 IItemFactory itemFactory)

Assigns to each edge of the graph a source port and target port coordinate pair.

This method is called by HierarchicLayoutCore after the sequencing phase.

Parameters:

graph - the input graph

layers - the given ILayers instance containing the elements in the layering

ldp - the ILayoutDataProvider containing layering information about the nodes and edges of the graph

itemFactory - the IItemFactory used temporarily for modifying the graph instance
