Interface GraphFactory

All Known Implementing Classes:

DefaultGraph2DFactory

public interface GraphFactory

Implementations of this interface provide a factory for graphs and elements within that graph. The created graph and graph elements must be compatible.

Method Summary

Edge	createEdge(Graph graph, Node source, Node target, Object hint) Returns a newly created edge object for the given graph.
Graph	createGraph(Object hint) Returns a newly created graph object.
Node	createNode(Graph graph, Object hint) Returns a newly created node object for the given graph.

Method Detail

createGraph

public Graph createGraph(Object hint)

Returns a newly created graph object. The given hint paramter may contain some context specific information that may guide the factory when creating the graph.

Parameters:

hint - context specific hint information.

Returns:

a newly created graph

createNode

public Node createNode(Graph graph,
                       Object hint)

Returns a newly created node object for the given graph. The given hint paramter may contain some context specific information that may guide the factory when creating the graph.

Parameters:

graph - the graph containing the newly created edge.

hint - context specific hint information.

Returns:

a newly created node

createEdge

public Edge createEdge(Graph graph,
                       Node source,
                       Node target,
                       Object hint)

Returns a newly created edge object for the given graph. The given hint parameter may contain some context specific information that may guide the factory when creating the graph.

Parameters:

graph - the graph containing the newly created edge.

source - the source node of the newly created edge.

target - the target node of the newly created edge.

hint - context specific hint information.

Returns:

a newly created edge
