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

Throws:

GraphMLWriteException

Parameters:

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

serializeContent

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

Write the content of an NodeLabel element.

Throws:

GraphMLWriteException

Parameters:

context - The current write context.

writer - The writer to use.

label - The label to write.

writeCustomModelElements

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

Write the representation of a custom label model.

Throws:

GraphMLWriteException

Parameters:

context - The current write context.

writer - The writer to use.

label - The label to write.

getModelName

protected String getModelName(NodeLabel label,
                              GraphMLWriteContext context)

Gets the symbolic name of a label model for the modelName attribute of the NodeLabel element.

Parameters:

label - The label whose model is written.

context - The current write context.

Returns:

The symbolic name of the label model.

getModelPosition

protected String getModelPosition(NodeLabel label,
                                  GraphMLWriteContext context)

Gets the symbolic name of a label model for the modelPosition attribute of the EdgeLabel element.

Parameters:

label - The label whose model is written.

context - The current write context.

Returns:

The symbolic name of the label model.
