Detailed Description

DisjointCommunityDetection 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.

Member Function Documentation

void com.sparsity.sparksee.algorithms.DisjointCommunityDetection.AddAllEdgeTypes ( )

Allows connectivity through all edge types of the graph.

The edges can be used in Any direction.

void com.sparsity.sparksee.algorithms.DisjointCommunityDetection.AddEdgeType ( int  type)

Allows connectivity through edges of the given type.

The edges can be used in Any direction.

Parameters
type[in] Edge type.
void com.sparsity.sparksee.algorithms.DisjointCommunityDetection.AddNodeType ( int  type)

Allows connectivity through nodes of the given type.

Parameters
typenull
void com.sparsity.sparksee.algorithms.CommunityDetection.Close ( )
inherited

Closes the CommunityDetection instance.

It must be called to ensure the integrity of all data.

void com.sparsity.sparksee.algorithms.DisjointCommunityDetection.ExcludeEdges ( com.sparsity.sparksee.gdb.Objects  edges)

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.
void com.sparsity.sparksee.algorithms.DisjointCommunityDetection.ExcludeNodes ( com.sparsity.sparksee.gdb.Objects  nodes)

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.
com.sparsity.sparksee.algorithms.DisjointCommunities com.sparsity.sparksee.algorithms.DisjointCommunityDetection.GetCommunities ( )

Returns the results generated by the execution of the algorithm.

These results contain information related to the disjoint communities found as the number of different components, the set of nodes contained in each component or many other data.

Returns
Returns an instance of the class DisjointCommunities which contain information related to the disjoint communities found.
boolean com.sparsity.sparksee.algorithms.CommunityDetection.IsClosed ( )
inherited

Gets if CommunityDetection instance has been closed or not.

See Also
Close()
Returns
TRUE if the CommunityDetection instance has been closed, FALSE otherwise.
void com.sparsity.sparksee.algorithms.DisjointCommunityDetection.Run ( )

Runs the algorithm in order to find the communities.

This method can be called only once.

void com.sparsity.sparksee.algorithms.DisjointCommunityDetection.SetMaterializedAttribute ( System.String  attributeName)

Creates a new common attribute type for all node types in the graph in order to store, persistently, the results related to the disjoint communities found while executing this algorithm.

Whenever the user wants to retrieve the results, even when the graph has been closed and opened again, it is only necessary to create a new instance of the class DisjointCommunities indicating the graph and the name of the common attribute type which stores the results. This instance will have all the information related to the disjoint communities found in the moment of the execution of the algorithm that stored this data.

It is possible to run the algorithm without specifying this parameter in order to avoid materializing the results of the execution.

Parameters
attributeName[in] The name of the common attribute type for all node types in the graph which will store persistently the results generated by the execution of the algorithm.
