Constructor & Destructor Documentation

◆ TwoLayerCrossMinSimDraw()

ogdf::TwoLayerCrossMinSimDraw::TwoLayerCrossMinSimDraw ( )
inline

Initializes a two-layer crossing minimization module.

Definition at line 43 of file TwoLayerCrossMinSimDraw.h.

Member Function Documentation

◆ call() [1/2]

void ogdf::TwoLayerCrossMinSimDraw::call ( Level L)
pure virtual

Performs crossing minimization for level L.

Parameters
Lis the level in the hierarchy on which nodes are permuted; the neighbor level (fixed level) is determined by the hierarchy.

Implements ogdf::LayerByLayerSweep.

Implemented in ogdf::SplitHeuristic.

◆ call() [2/2]

virtual void ogdf::TwoLayerCrossMinSimDraw::call ( Level L,
const EdgeArray< uint32_t > *  esg 
)
pure virtual

Performs crossing minimization for level L.

Parameters
Lis the level in the hierarchy on which nodes are permuted; the neighbor level (fixed level) is determined by the hierarchy.
esgpoints to an edge array which specifies to which subgraphs an edge belongs; there are up to 32 possible subgraphs each of which is represented by a bit of an uint32_t.

Implemented in ogdf::SplitHeuristic.

◆ clone()

virtual TwoLayerCrossMinSimDraw* ogdf::TwoLayerCrossMinSimDraw::clone ( ) const
pure virtual

Returns a new instance of the two-layer crossing minimization module with the same option settings.

Implements ogdf::LayerByLayerSweep.

Implemented in ogdf::SplitHeuristic.
