DataHandlerhas already been loaded. A return value of
truemeans that a call to
getDataHandler()will not block or will retrieve the
DataHandlerwithout overhead. Note the return value of this method for a given instance of this class may change over time due to events other than a call to
getDataHandler()on the same instance. E.g. a call to
getDataHandler()on one instance may change the return value of the method on another instance (because the
DataHandlerobjects can only be loaded in a certain sequence).
