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 scope KeyScope.NODE and name 'http://www.yworks.com/xml/yfiles-graphml/1.0/expansionstate'.
