graph - the data of the first graph in the input is stored here.

Method Detail

createEdge

public Edge createEdge(GraphMLParseContext context,
                       Node sourceNode,
                       Port sourcePort,
                       Node targetNode,
                       Port targetPort)

Creates an edge for the given context and the provided source and target nodes or ports.

Specified by:

createEdge in interface GraphElementFactory

Parameters:

context - The context from which the graph, the CreationProperties, and the GraphMLParseContext.getObjectStack() can be queried.

sourceNode - The source node for the edge.

sourcePort - The source port for the edge, if specified, otherwise null.

targetNode - The target node for the edge.

targetPort - The target port for the edge, if specified, otherwise null.

Returns:

A newly created edge.

createNode

public Node createNode(GraphMLParseContext context)

Creates a node for the given context and set grouping information if the node is found to be the child of a group node.

Specified by:

createNode in interface GraphElementFactory

Parameters:

context - The context from which the graph, the CreationProperties, and the GraphMLParseContext.getObjectStack() can be queried.

Returns:

A newly created node

createPort

public Port createPort(GraphMLParseContext context,
                       Node owner)

Creates a port object that is owned by owner.

Specified by:

createPort in interface GraphElementFactory

Parameters:

context - The parse context.

owner - The owner of the port object.

Returns:

A new port object at the center of the provided owner.
