Interface IGraphMLCreator

public interface IGraphMLCreator

The IGraphMLCreator interface allows an object to manage the creation procedure of a graph during the GraphML file parsing.
The creation of the graph, the nodes and the edges is delegated to the IGraphMLCreator.
This interface is useful when the user override the RelationalAgent class adding some properties and methods, since the GraphML class loads a graph from a file, creating the default RelationalAgent classes. How to load graphs.
The GraphML class is able to parse a standard GraphML formatted file and creates a org._3pq.jgrapht.DirectedWeightedMultigraph. All the nodes are RelationalAgent instances. If you want to create different kind of graph or different nodes, you have to create a class implementing the IGraphMLCreator, which will be delegated to create objects. See the jas.graph.IGraphMLCreator for mode details.

Method Summary

IRelationalAgent	createNewNode(int id, java.util.Map attributes) It is called when a the GraphML parser finds a tag.
void	getNewGraph(org._3pq.jgrapht.Graph newGraph) Return a new graph created by the GraphML parser.

Method Detail

createNewNode

IRelationalAgent createNewNode(int id,
                               java.util.Map attributes)

It is called when a the GraphML parser finds a tag.

Parameters:

attributes - A key-value map of attributes contained by the GraphML file. The required attributes (id, label, x, y) are always present in the map.

Returns:

A new IRelationalAgent node. Warning the node must be appended to the graph by the IGraphMLCreator instance.

getNewGraph

void getNewGraph(org._3pq.jgrapht.Graph newGraph)

Return a new graph created by the GraphML parser.
