Initializes a new Handler instance.

Method Detail

onHandleSerialization

public void onHandleSerialization(SerializationEvent event)
                           throws GraphMLWriteException

Serializes NodeScaledPortLocationModel models and model parameters. Creates <NodeScaledPortLocationModel> elements.

Calls writeAttributes.

Specified by:

onHandleSerialization in interface SerializationHandler

Parameters:

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

Throws:

GraphMLWriteException

writeAttributes

public void writeAttributes(PortLocationModelParameter parameter,
                            XmlWriter writer,
                            GraphMLWriteContext context)
                     throws GraphMLWriteException

Writes the specified port location model parameter as attributes for the given XmlWriter's current element.

Called from onHandleSerialization.

Parameters:

parameter - the port location model parameter to serialize. Must be an instance created by NodeScaledPortLocationModel.

writer - the XmlWriter used for serialization.

context - the current write context.

Throws:

GraphMLWriteException

onHandleDeserialization

public void onHandleDeserialization(DeserializationEvent event)
                             throws GraphMLParseException

Deserializes NodeScaledPortLocationModel models and model parameters. Parses <Geometry> elements with <NodeScaledPortLocationModel> children.

Calls isModelElement and readAttributes.

Specified by:

onHandleDeserialization in interface DeserializationHandler

Parameters:

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

Throws:

GraphMLParseException

readAttributes

public PortLocationModelParameter readAttributes(org.w3c.dom.NamedNodeMap attributes,
                                                 GraphMLParseContext context)
                                          throws GraphMLParseException

Reads the given XML attributes to create a port location model parameter for NodeScaledPortLocationModel.

Calls createModel to create a model instance for the returned model parameter.

Called from onHandleDeserialization.

Parameters:

attributes - the XML attributes to read.

context - the current parse context.

Returns:

a new NodeScaledPortLocationModel model parameter instance.

Throws:

GraphMLParseException

writeAttributes(PortLocationModelParameter, y.io.graphml.output.XmlWriter, y.io.graphml.output.GraphMLWriteContext)

createModel

protected NodeScaledPortLocationModel createModel(org.w3c.dom.NamedNodeMap attributes,
                                                  GraphMLParseContext context)
                                           throws GraphMLParseException

Creates a new instance of NodeScaledPortLocationModel.

Called from readAttributes.

Parameters:

attributes - the XML attributes for which the model is created.

context - the current parse context.

Returns:

a new instance of NodeScaledPortLocationModel.

Throws:

GraphMLParseException

isModelElement

protected boolean isModelElement(org.w3c.dom.Node node)

Determines whether or not the given XML node is a Element that stores NodeScaledPortLocationModel data.

Called from onHandleDeserialization.

Parameters:

node - the XML node to check.

Returns:

true if the given XML node is a Element that stores NodeScaledPortLocationModel data; false otherwise.

isGeometryElement

public static boolean isGeometryElement(org.w3c.dom.Node node)

Determines whether or not the given XML node is a <Geometry> element.

Parameters:

node - the XML node to check.

Returns:

true if the given XML node is a <Geometry> element; false otherwise.
