Detailed Description

Simple cluster sets.

A cluster set maintains a subset S of the clusters contained in an associated clustered graph. This kind of cluster set only provides efficient operation for testing membership, insertion, and clearing the set.

Constructor & Destructor Documentation

ClusterSetSimple()

ogdf::ClusterSetSimple::ClusterSetSimple ( const ClusterGraph &  C )

inlineexplicit

Creates an empty cluster set associated with clustered graph C.

Definition at line 54 of file ClusterSet.h.

Member Function Documentation

clear()

void ogdf::ClusterSetSimple::clear ( )

inline

Removes all clusters from S.

After this operation, S is empty and still associated with the same clustered graph. The runtime of this operations is O(k), where k is the number of clusters in S before this operation.

Definition at line 80 of file ClusterSet.h.

clusters()

const SListPure< cluster > & ogdf::ClusterSetSimple::clusters ( ) const

inline

Returns a reference to the list of clusters contained in S.

This list can be used for iterating over all clusters in S.

Definition at line 103 of file ClusterSet.h.

insert()

void ogdf::ClusterSetSimple::insert ( cluster  c )

inline

Inserts cluster c into S.

This operation has constant runtime.

Precondition

c is a cluster in the associated clustered graph.

Definition at line 65 of file ClusterSet.h.

isMember()

bool ogdf::ClusterSetSimple::isMember ( cluster  c ) const

inline

Returns true if cluster c is contained in S, false otherwise.

This operation has constant runtime.

Precondition

c is a cluster in the associated graph.

Definition at line 94 of file ClusterSet.h.

Member Data Documentation

m_clusters

SListPure<cluster> ogdf::ClusterSetSimple::m_clusters

private

Definition at line 110 of file ClusterSet.h.

m_isContained

ClusterArray<bool> ogdf::ClusterSetSimple::m_isContained

private

m_isContained[c] is true iff c is contained in S
