Detailed Description

Inserts edges optimally into an embedding.

Iteratively inserts edges (optimally for each insertion step) into a possibly fixed embedding. Note that by default the embedding is not fixed and will be changed regardless of the input. If the input can be guaranteed to be a planar embedding you may flip keepEmbedding to preserve it.

◆ FixedEmbeddingInserter() [1/2]

ogdf::FixedEmbeddingInserter::FixedEmbeddingInserter ( )

Creates an instance of fixed embedding edge inserter with default settings.

◆ FixedEmbeddingInserter() [2/2]

ogdf::FixedEmbeddingInserter::FixedEmbeddingInserter ( const FixedEmbeddingInserter & inserter )

Creates an instance of fixed embedding edge inserter with the same settings as inserter.

◆ ~FixedEmbeddingInserter()

ogdf::FixedEmbeddingInserter::~FixedEmbeddingInserter ( )

inline

Destructor.

Member Function Documentation

◆ clone()

virtual EdgeInsertionModule * ogdf::FixedEmbeddingInserter::clone ( ) const

overridevirtual

Returns a new instance of the fixed embedding inserter with the same option settings.

Implements ogdf::EdgeInsertionModule.

◆ doCall()

virtual ReturnType ogdf::FixedEmbeddingInserter::doCall	(	PlanRepLight &	pr,
		const Array< edge > &	origEdges,
		const EdgeArray< int > *	costOrig,
		const EdgeArray< bool > *	pForbiddenOrig,

	)

overrideprivatevirtual

Implements the algorithm call.

Implements ogdf::EdgeInsertionModule.

◆ keepEmbedding()

void ogdf::FixedEmbeddingInserter::keepEmbedding ( bool keep )

inline

Sets the option keepEmbedding to keep.

This option determines if the planar embedding of the planarized representation PG passed to the call-method is preserved, or if always a new embedding is computed. If keepEmbedding is set to true, PG must always be planarly embedded.

Definition at line 96 of file FixedEmbeddingInserter.h.

◆ keepEmbeding()

bool ogdf::FixedEmbeddingInserter::keepEmbeding ( ) const

inline

Returns the current setting of option keepEmbedding.

Definition at line 99 of file FixedEmbeddingInserter.h.

◆ operator=()

FixedEmbeddingInserter & ogdf::FixedEmbeddingInserter::operator= ( const FixedEmbeddingInserter & inserter )

Assignment operator. Copies option settings only.

◆ percentMostCrossed() [1/2]

double ogdf::FixedEmbeddingInserter::percentMostCrossed ( ) const

inline

Returns the current setting of option percentMostCrossed.

Definition at line 88 of file FixedEmbeddingInserter.h.

◆ percentMostCrossed() [2/2]

void ogdf::FixedEmbeddingInserter::percentMostCrossed ( double percent )

inline

Sets the option percentMostCrossed to percent.

This option determines the portion of most crossed edges used if the remove-reinsert method is set to RemoveReinsertType::MostCrossed. This portion is number of edges * percentMostCrossed() / 100.

Definition at line 85 of file FixedEmbeddingInserter.h.

◆ removeReinsert() [1/2]

RemoveReinsertType ogdf::FixedEmbeddingInserter::removeReinsert ( ) const

inline

Returns the current setting of the remove-reinsert postprocessing method.

Definition at line 78 of file FixedEmbeddingInserter.h.

◆ removeReinsert() [2/2]

void ogdf::FixedEmbeddingInserter::removeReinsert ( RemoveReinsertType rrOption )

inline

Sets the remove-reinsert postprocessing method.

This might alter the input embedding.

Definition at line 75 of file FixedEmbeddingInserter.h.

◆ runsPostprocessing()

int ogdf::FixedEmbeddingInserter::runsPostprocessing ( ) const

inline

Returns the number of runs performed by the remove-reinsert method after the algorithm has been called.

Definition at line 107 of file FixedEmbeddingInserter.h.
