Deprecated. Use RealizerSerializerManager instead for /* instance specific registration.

acceptKey

public boolean acceptKey(NamedNodeMap attributes,
                         int scopeType)

Description copied from interface: DOMInputHandler

This method defines whether a specific key/data pair is handled by the input handler. When it returns true, each occurence of data elements which match the id of the key element are forwarded to the input handler.

Parameters:

attributes - the attributes of the key tag.

scopeType - the scope for which the key is defined. One of GraphMLConstants.SCOPE_ALL, GraphMLConstants.SCOPE_EDGE, GraphMLConstants.SCOPE_ENDPOINT, GraphMLConstants.SCOPE_GRAPH, GraphMLConstants.SCOPE_NODE, GraphMLConstants.SCOPE_PORT, GraphMLConstants.SCOPE_HYPEREDGE.

parseData

protected void parseData(DOMGraphMLParseContext context,
                         Graph graph,
                         Object edge,
                         boolean defaultMode,
                         Node domNode)

Description copied from class: AbstractDOMInputHandler

Parses the data.

Specified by:

parseData in class AbstractDOMInputHandler

Parameters:

context - The context in which the parser is.

graph - The current graph in the parse context.

edge - The current node/edge in the parse context.

defaultMode - Whether default data or real data is read.

domNode - The DOM node which is actually processed.

parseRealizer

public static EdgeRealizer parseRealizer(Graph2D graph,
                                         Edge yEdge,
                                         Node node,
                                         GraphMLParseContext context)

applyDefault

protected void applyDefault(DOMGraphMLParseContext context,
                            Graph graph,
                            Object nodeedge)

Description copied from class: AbstractDOMInputHandler

Apply default data.

Specified by:

applyDefault in class AbstractDOMInputHandler

Parameters:

context - The context in which the parser is.

graph - The current graph in the parse context.

nodeedge - The current node/edge in the parse context.
