public class SharedDataInputHandler

extends AbstractInputHandlerProvider

Input handler that enables parsing of shared references.

Constructor Summary

SharedDataInputHandler()

Method Summary

boolean	acceptKey(org.w3c.dom.Element keyDefinition) This method is called by AbstractInputHandlerProvider.onQueryInputHandler(y.io.graphml.input.QueryInputHandlersEvent) and shall decide if the given keyDefinition shall be accepted so that this input handler gets provided for the event.
DeserializationHandler	getDeserializer() Returns a deserializer that can parse xml elements which reference shared elements.
ParsePrecedence	getPrecedence() This input handler shall be used before any other one.
protected java.lang.Object	parseDataCore(GraphMLParseContext context, org.w3c.dom.Node node)
protected void	setValue(GraphMLParseContext context, java.lang.Object key, java.lang.Object data) This method does nothing

Method Detail

getDeserializer

public DeserializationHandler getDeserializer()

Returns a deserializer that can parse xml elements which reference shared elements.

parseDataCore

protected java.lang.Object parseDataCore(GraphMLParseContext context,
                                         org.w3c.dom.Node node)
                                  throws GraphMLParseException

Throws:

GraphMLParseException

setValue

protected void setValue(GraphMLParseContext context,
                        java.lang.Object key,
                        java.lang.Object data)
                 throws GraphMLParseException

This method does nothing

Parameters:

context - The context.

key - The key.

data - The data.

Throws:

GraphMLParseException

acceptKey

public boolean acceptKey(org.w3c.dom.Element keyDefinition)

This method is called by AbstractInputHandlerProvider.onQueryInputHandler(y.io.graphml.input.QueryInputHandlersEvent) and shall decide if the given keyDefinition shall be accepted so that this input handler gets provided for the event.

Specified by:

acceptKey in class AbstractInputHandlerProvider

Parameters:

keyDefinition - The key definition to check.

Returns:

true for key elements with name 'sharedData', type KeyType.COMPLEX and scope KeyScope.GRAPH

getPrecedence

public ParsePrecedence getPrecedence()

This input handler shall be used before any other one.

Returns:

ParsePrecedence.FIRST
