Method Detail

parseEdgeLabel

protected void parseEdgeLabel(GraphMLParseContext context,
                              org.w3c.dom.Node root,
                              EdgeLabel label)
                       throws GraphMLParseException

Configure an existing label with the data in root.

Parameters:

context - The current parse context.

root - The DOM node to parse.

label - The label instance to configure.

Throws:

GraphMLParseException

parseIconAttribute

protected void parseIconAttribute(GraphMLParseContext context,
                                  org.w3c.dom.Node root,
                                  EdgeLabel label)
                           throws GraphMLParseException

Parses the attribute that references the label's icon resource.

Parameters:

context - The current parse context.

root - The DOM node to parse.

label - The label instance to configure.

Throws:

GraphMLParseException

parsePreferredPlacementDescriptor

protected void parsePreferredPlacementDescriptor(GraphMLParseContext context,
                                                 org.w3c.dom.Node root,
                                                 EdgeLabel label)
                                          throws GraphMLParseException

Throws:

GraphMLParseException

parseLabelModel

protected void parseLabelModel(GraphMLParseContext context,
                               org.w3c.dom.Node root,
                               EdgeLabel label)
                        throws GraphMLParseException

Configure the label model of an existing label with the data in root.

Parameters:

context - The current parse context.

root - The DOM node to parse that contains the label model data.

label - The label instance to configure.

Throws:

GraphMLParseException

createLabel

protected EdgeLabel createLabel(GraphMLParseContext context,
                                org.w3c.dom.Node root)

Create a new label instance from the data in root.

Parameters:

context - The current parse context.

root - The DOM node to parse that contains the label model data.

Returns:

A new EdgeLabel instance.

onHandleDeserialization

public void onHandleDeserialization(DeserializationEvent event)
                             throws GraphMLParseException

Description copied from interface: DeserializationHandler

Callback method to handle the deserialization of the data contained in event.

If this callback could deserialize the data in event, it should assign the deserialization result to the event's DeserializationEvent.setResult(Object) property.

Specified by:

onHandleDeserialization in interface DeserializationHandler

Parameters:

event - Event that contains all data that is needed for deserialization.

Throws:

GraphMLParseException
