| virtual void ogdf::LayoutModule::call | ( | GraphAttributes & | GA | ) | [pure virtual] |
Computes a layout of graph GA.
This method is the actual algorithm call and must be implemented by derived classes.
| GA | is the input graph and will also be assigned the layout information. |
Implemented in ogdf::PreprocessorLayout, ogdf::TutteLayout, ogdf::DavidsonHarelLayout, ogdf::FastMultipoleEmbedder, ogdf::FastMultipoleMultilevelEmbedder, ogdf::FMMMLayout, ogdf::GEMLayout, ogdf::MixedForceLayout, ogdf::MMMExampleFastLayout, ogdf::MMMExampleNiceLayout, ogdf::MMMExampleNoTwistLayout, ogdf::ModularMultilevelMixer, ogdf::ScalingLayout, ogdf::SpringEmbedderFR, ogdf::SpringEmbedderFRExact, ogdf::SpringEmbedderKK, ogdf::StressMajorization, ogdf::SugiyamaLayout, ogdf::BalloonLayout, ogdf::CircularLayout, ogdf::ForceLayoutModule, ogdf::GridLayoutModule, ogdf::ComponentSplitterLayout, ogdf::PlanarizationLayout, ogdf::RadialTreeLayout, ogdf::TreeLayout, ogdf::DominanceLayout, ogdf::UpwardPlanarizationLayout, and ogdf::VisibilityLayout.
| virtual void ogdf::LayoutModule::call | ( | MultilevelGraph & | MLG | ) | [inline, virtual] |
Computes a layout of graph MLG.
This method can be implemented optionally to allow a LayoutModule to modify the Graph. This allows some Layout Algorithms to save Memory, compared to a normal call(GA) DO NOT implement this if you are not sure whether this would save you Memory! This Method only helps if the Graph is already in the MultiLevelGraph Format (or can be converted without creating a copy) AND the Layout would need a copy otherwise. All Incremental Layouts (especially energy based) CAN be called by ModularMultilevelMixer. The standard implementation converts the MLG to GA and uses call(GA).
If implemented, the following Implementation of call(GA) is advised to ensure consistent behaviour of the two call Methods: void YourLayout::call(GraphAttributes &GA) { MultilevelGraph MLG(GA); call(MLG); MLG.exportAttributes(GA); }
| MLG | is the input graph and will also be assigned the layout information. |
