Method Detail

newAbstractGraph

public AbstractGraph newAbstractGraph(AbstractVertexSet nodeSet,
                                      AbstractEdgeSet edgeSet)

Constructs a new abstract Graph based on a node set and an edge set.

Specified by:

newAbstractGraph in interface AbstractGraphFactory

Parameters:

nodeSet - the node set of the new graph

edgeSet - the edge set of the new graph

newAbstractGraph

public AbstractGraph newAbstractGraph(AbstractGraph graph)

Constructs a sub graph of a graph. A sub graph is a graph wich node set, respictevely edge set, is included in the original node set, respictevely, in the original edge set. The constructed graph is empty.

Specified by:

newAbstractGraph in interface AbstractGraphFactory

Parameters:

graph - the father graph of the graph to construct.

newAbstractCopyGraph

public AbstractGraph newAbstractCopyGraph(AbstractGraph graph,
                                          boolean copyElements)

Constructs a copy of a graph. This constructor allows to copy a graph and all its parts.

Specified by:

newAbstractCopyGraph in interface AbstractGraphFactory

Parameters:

copyElements - which indicates if the nodes and edges have to be copied. If not, then only the set are duplicated.

graph - the graph to copy.

newAbstractVertexSet

public AbstractVertexSet newAbstractVertexSet()

Default node set constructor.

Specified by:

newAbstractVertexSet in interface AbstractGraphFactory

newAbstractVertexSet

public AbstractVertexSet newAbstractVertexSet(AbstractVertexSet nodeSet)

Constructs a new node set based on a node set.

Specified by:

newAbstractVertexSet in interface AbstractGraphFactory

Parameters:

nodeSet - the node set used as base to the node set.

Returns:

an abstract node set empty.

newAbstractVertex

public AbstractVertex newAbstractVertex()

Constructs a node.

Specified by:

newAbstractVertex in interface AbstractGraphFactory

newAbstractEdgeSet

public AbstractEdgeSet newAbstractEdgeSet(AbstractVertexSet nodeSet)

Constructs a new edge set based on a node set.

Specified by:

newAbstractEdgeSet in interface AbstractGraphFactory

Parameters:

nodeSet - the node set used as base to the edge set.

Returns:

an abstract edge set empty.

newAbstractEdgeSet

public AbstractEdgeSet newAbstractEdgeSet(AbstractEdgeSet edgeSet)

Constructs a new edge set which is a sub set of an other edge set.

Specified by:

newAbstractEdgeSet in interface AbstractGraphFactory

Parameters:

edgeSet - the edge set used as base to the edge set.

Returns:

an abstract edge set empty.

newAbstractEdgeSet

public AbstractEdgeSet newAbstractEdgeSet(AbstractEdgeSet es,
                                          AbstractVertexSet abstractNodeSet)

Constructs a new edge set which is as sub set of an other edge set and based on a node set. This is the most generic constructor. It permits to use a specific node set as the base of the new edge set. Then, it permits to associate the new edge set with an other edge set: the new is a sub set of the other.

Specified by:

newAbstractEdgeSet in interface AbstractGraphFactory

Parameters:

es - the father edge set.

abstractNodeSet - the base of nodes of the new edge set.

Returns:

an abstract edge set empty.

newAbstractEdge

public AbstractEdge newAbstractEdge(AbstractVertex n0,
                                    AbstractVertex n1)

Constructs an edge beetween two nodes.

Specified by:

newAbstractEdge in interface AbstractGraphFactory

Parameters:

n0 - the first node.

n1 - the second node.

Returns:

the constructed edge.

newAbstractPath

public AbstractPath newAbstractPath(AbstractEdgeSet edgeSet)

Constructs a new chain based on a edge set. The chain is empty when constructed. Only edges from the edgeSet can be added in the chain. It modelize the fact that the chain is a subgraph of the main graph. Then, use the edge set of the graph to construct new chains.

Specified by:

newAbstractPath in interface AbstractGraphFactory

Parameters:

edgeSet - the base of the chain

Returns:

a empty chain.

newAbstractCopyPath

public AbstractPath newAbstractCopyPath(AbstractPath chain)

Constructs a copy of a chain. This constructor allows to copy a chain and all its parts. Nodes and edges are not copied.

Specified by:

newAbstractCopyPath in interface AbstractGraphFactory

Parameters:

chain - the chain to copy.
