Detailed Description

Calls modified algorithms for simdraw instances.

Runs special algorithms suitable for simultaneous drawing on current SimDraw instance. The algorithms take care of all necessary GraphAttributes activations and take over calculated coordinates and dummy nodes.

A typical use of SimDrawCaller involves a predefined SimDraw instance on which SimDrawCaller works.

SimDraw SD;
...
SimDrawCaller SDC(SD);
SDC.callSubgraphPlanarizer();

Member Function Documentation

callPlanarizationLayout()

void ogdf::SimDrawCaller::callPlanarizationLayout

(

)

runs UMLPlanarizationLayout with modified inserter

Runs UMLPlanarizationLayout with callSimDraw and retransfers node coordinates and dummy node bend to current simdraw instance.

Automatically activates GraphAttributes::nodeGraphics.
Automatically activates GraphAttributes::edgeGraphics.

callSubgraphPlanarizer()

int ogdf::SimDrawCaller::callSubgraphPlanarizer	(	int	cc = 0,
		int	numberOfPermutations = 1
	)

runs SubgraphPlanarizer with modified inserter

Runs SubgraphPlanarizer on connected component cc with simdraw call. Integer edge costs of GraphAttributes are used (1 for each edge if not available).

Modifies graph by inserting dummy nodes for each crossing. All dummy nodes are marked as dummy. (Method SimDrawColorizer::addColorNodeVersion is recommended for visualizing dummy nodes.)

No layout is calculated. The result is a planar graph.

callSugiyamaLayout()

void ogdf::SimDrawCaller::callSugiyamaLayout

(

)

runs SugiyamaLayout with modified SplitHeuristic

Runs special call of SugiyamaLayout using SugiyamaLayout::setSubgraphs(). Saves node coordinates and dummy node bends in current simdraw instance.

Uses TwoLayerCrossMinSimDraw object to perform crossing minimization. The default is SplitHeuristic.

Automatically activates GraphAttributes::nodeGraphics.
Automatically activates GraphAttributes::edgeGraphics.

updateESG()

void ogdf::SimDrawCaller::updateESG ( )

private

updates m_esg

Should be called whenever graph changed and current basic graph membership is needed.
