Method Detail

parseNodeLabel

protected void parseNodeLabel(GraphMLParseContext context,
                              Node root,
                              NodeLabel label)
                       throws GraphMLParseException

Configure an existing label with the data in root.

Throws:

GraphMLParseException

Parameters:

context - The current parse context.

root - The DOM node to parse.

label - The label instance to configure.

parseLabelModel

protected void parseLabelModel(GraphMLParseContext context,
                               Node root,
                               NodeLabel label)
                        throws GraphMLParseException

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

Throws:

GraphMLParseException

Parameters:

context - The current parse context.

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

label - The label instance to configure.

createLabel

protected NodeLabel createLabel(GraphMLParseContext context,
                                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 NodeLabel 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

Throws:

GraphMLParseException

Parameters:

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