Class Graph2DElementFactory

java.lang.Object
  y.io.graphml.graph2d.Graph2DElementFactory

All Implemented Interfaces:

GraphElementFactory

public class Graph2DElementFactory
extends java.lang.Object
implements GraphElementFactory

The basic implementation of the GraphElementFactory interface for use with the default Graphs.

This implementation does not create any hierarchy information, you should use a decoration implementation like HierarchyManagerBasedGraphElementFactory instead.

This uses the CreationProperties from the GraphMLParseContext to create the items with the correct initial values if they have been put into the creation properties by InputHandler implementations that have been invoked before the creation of the items.

Constructor Summary

Graph2DElementFactory()

Method Summary

Edge	createEdge(GraphMLParseContext context, Node sourceNode, Port sourcePort, Node targetNode, Port targetPort) Creates an normal edge for the given context and the provided source and target nodes or ports.
Node	createNode(GraphMLParseContext context) Creates and configures a normal node for the given context.
Port	createPort(GraphMLParseContext context, Node owner) Creates NodePort instances that are bound to the specified node's visual representation (its NodeRealizer).

public Graph2DElementFactory()

Method Detail

createNode

public Node createNode(GraphMLParseContext context)

Creates and configures a normal node for the given context.

This implementation uses node realizer and layout information from the context if available

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

createEdge

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

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

This implementation uses edge realizer and layout information from the context if available

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.

createPort

public Port createPort(GraphMLParseContext context,
                       Node owner)

Creates NodePort instances that are bound to the specified node's visual representation (its NodeRealizer).

Specified by:

createPort in interface GraphElementFactory

Parameters:

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

owner - The owner of the port object

Returns:

a new NodePort.
