Detailed Description

CommunityDetection class.

Any class implementing this abstract class can be used to solve a problem related to graph connectivity as finding the strongly connected components, finding the weakly connected components.

Check out the 'Algorithms' section in the SPARKSEE User Manual for more details on this.

Constructor & Destructor Documentation

CommunityDetection::CommunityDetection ( sparksee::gdb::Session & s )

protected

Creates a new instance of CommunityDetection.

Parameters

s	[in] Session to get the graph from and calculate the communities

Member Function Documentation

void CommunityDetection::AddAllEdgeTypes ( sparksee::gdb::EdgesDirection direction )

protected

Allows connectivity through all edge types of the graph.

Parameters

d	[in] Edge direction.

void CommunityDetection::AddEdgeType	(	sparksee::gdb::type_t	type,
		sparksee::gdb::EdgesDirection	direction
	)

protected

Allows connectivity through edges of the given type.

Parameters

t	[in] Edge type.
d	[in] Edge direction.

virtual void CommunityDetection::ExcludeEdges ( sparksee::gdb::Objects & edges )

virtual

Set which edges can't be used.

This will replace any previously specified set of excluded edges. Should only be used to exclude the usage of specific edges from allowed edge types because it's less efficient than not allowing an edge type.

Parameters

edges [in] A set of edge identifiers that must be kept intact until the destruction of the class.

virtual void CommunityDetection::ExcludeNodes ( sparksee::gdb::Objects & nodes )

virtual

Set which nodes can't be used.

This will replace any previously specified set of excluded nodes. Should only be used to exclude the usage of specific nodes from allowed node types because it's less efficient than not allowing a node type.

Parameters

nodes [in] A set of node identifiers that must be kept intact until the destruction of the class.

virtual void CommunityDetection::IncludeEdges ( sparksee::gdb::Objects & edges )

virtual

Set additional edges that can be used.

This will replace any previously specified set of include edges. Using this optional method adds valid edges to the edges of any edge type explicitly set as a valid type. Should only be used to include specific small sets of edges because it's less efficient than just using an edge type. For any edge to be used, both nodes must be also valid.

Parameters

edges [in] A set of edge identifiers that must be kept intact until the destruction of the class.

virtual void CommunityDetection::IncludeNodes ( sparksee::gdb::Objects & nodes )

virtual

Set additional nodes that can be used.

This will replace any previously specified set of include nodes. Using this optional method adds valid nodes to the nodes of any node type explicitly set as a valid type. Should only be used to include specific small sets of nodes because it's less efficient than just using a node type.

Parameters

nodes [in] A set of node identifiers that must be kept intact until the destruction of the class.

virtual void CommunityDetection::Run ( )

pure virtual

Runs the algorithm in order to find the connected components.

This method can be called only once.

Implemented in DisjointCommunityDetection, and CommunitiesSCD.

void CommunityDetection::SetNodesNotVisited ( )

protected

Set all the selected nodes in nodesNotVisited.

That's all the nodes of the allowed node types but not the excluded ones.
