## 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.

## ◆ ClusterSetSimple()

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

Creates an empty cluster set associated with clustered graph C.

Definition at line 56 of file ClusterSet.h.

## ◆ ~ClusterSetSimple()

 ogdf::ClusterSetSimple::~ClusterSetSimple ( )
inline

Definition at line 59 of file ClusterSet.h.

## ◆ 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 83 of file ClusterSet.h.

## ◆ clusters()

 const SListPure& 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 107 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 67 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 98 of file ClusterSet.h.

## ◆ m_clusters

 SListPure ogdf::ClusterSetSimple::m_clusters
private

The list of clusters contained in S.

Definition at line 116 of file ClusterSet.h.

## ◆ m_isContained

 ClusterArray ogdf::ClusterSetSimple::m_isContained
private

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