Member Function Documentation

call()

ReturnType ogdf::UMLCrossingMinimizationModule::call ( PlanRepUML &  prUML, int  cc, int &  crossingNumber, const EdgeArray< int > *  pCostOrig = nullptr  )

inline

Computes a planarized representation of the input graph.

Parameters

prUML	represents the input graph as well as the computed planarized representation after the call. prUML has to be initialzed as a PlanRep of the input graph and is modified to obatain the planarized representation (crossings are replaced by dummy vertices with degree four).
cc	is the index of the connected component in prUML that is considered.
crossingNumber	is assigned the number of crossings.
pCostOrig	points to an edge array (of the original graph) that gives the cost of each edge. May be a 0-pointer, in which case all edges have cost 1.

Returns

the status of the result.

Definition at line 70 of file UMLCrossingMinimizationModule.h.

checkCrossingGens()

static bool ogdf::UMLCrossingMinimizationModule::checkCrossingGens ( const PlanRepUML &  prUML )

static

Checks if the planarized represenation contains crossing generalizations.

clone()

virtual UMLCrossingMinimizationModule* ogdf::UMLCrossingMinimizationModule::clone ( ) const

pure virtual

Returns a new instance of the UML crossing minimization module with the same option settings.

Implemented in ogdf::SubgraphPlanarizerUML.

doCall()

virtual ReturnType ogdf::UMLCrossingMinimizationModule::doCall ( PlanRepUML &  prUML, int  cc, const EdgeArray< int > *  pCostOrig, int &  crossingNumber  )

protectedpure virtual

Actual algorithm call that needs to be implemented by derived classes.
