Method Summary

void	applyDefault(GraphMLParseContext context) This method is invoked when no data tag is defined, and the default value should be applied.
ParsePrecedence	getPrecedence() Gets the parse precedence that is associated with this instance.
void	parseData(GraphMLParseContext context, Node node) This method is invoked each time a data element with matching key is processed.

Method Detail

getPrecedence

ParsePrecedence getPrecedence()

Gets the parse precedence that is associated with this instance.

Returns:

The parse precedence for this instance.

parseData

void parseData(GraphMLParseContext context,
               Node node)
               throws GraphMLParseException

This method is invoked each time a data element with matching key is processed.

Throws:

GraphMLParseException

Parameters:

context - the current parse context.

node - the DOM node representing the data element.

applyDefault

void applyDefault(GraphMLParseContext context)
                  throws GraphMLParseException
