                          int edgedefault)

Description copied from class: YGraphElementFactory

Creates the graph, should set up data with attributes.

Specified by:

createGraph in interface GraphElementFactory

Overrides:

createGraph in class YGraphElementFactory

Returns:

java.lang.Object

createNode

public Object createNode(GraphMLParseContext context,
                         String id)

Description copied from class: YGraphElementFactory

Creates a node on the passed graph, could be set up with attributes passed by.

Specified by:

createNode in interface GraphElementFactory

Overrides:

createNode in class YGraphElementFactory

createEdge

public Object createEdge(GraphMLParseContext context,
                         String id,
                         Object source,
                         Object target,
                         Object sourceport,
                         Object targetport,
                         boolean directed)

Description copied from class: YGraphElementFactory

This method creates an edge on the graph, between nodes source and target. Moreover the attributes are passed with the creation-request, so the application could set up all data, gaining from this parameter.

Specified by:

createEdge in interface GraphElementFactory

Overrides:

createEdge in class YGraphElementFactory
