Method Detail

onHandleSerialization

public void onHandleSerialization(SerializationEvent event)
                           throws GraphMLWriteException

Description copied from interface: SerializationHandler

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

If this callback could serialize the data in event, it should set the SerializationEvent.setHandled(boolean) property to true to prevent further serialization code from processing this data.

Specified by:

onHandleSerialization in interface SerializationHandler

Parameters:

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

Throws:

GraphMLWriteException

serializeContent

protected void serializeContent(NodeLabel label,
                                XmlWriter writer,
                                GraphMLWriteContext context)
                         throws GraphMLWriteException

Write the content of an NodeLabel element.

Parameters:

context - The current write context.

writer - The writer to use.

label - The label to write.

Throws:

GraphMLWriteException

writeIconAttribute

protected void writeIconAttribute(NodeLabel label,
                                  XmlWriter writer,
                                  GraphMLWriteContext context)
                           throws GraphMLWriteException

Writes the attribute that references the icon resource.

Parameters:

context - The current write context.

writer - The writer to use.

label - The label to write.

Throws:

GraphMLWriteException

writeCustomModelElements

protected void writeCustomModelElements(NodeLabel label,
                                        XmlWriter writer,
                                        GraphMLWriteContext context)
                                 throws GraphMLWriteException

Write the representation of a custom label model.

Parameters:

context - The current write context.

writer - The writer to use.

label - The label to write.

Throws:

GraphMLWriteException

getModelName

protected java.lang.String getModelName(NodeLabel label,
                                        GraphMLWriteContext context)
