/*!
    \class QLandmarkIdFetchRequest
    \brief The QLandmarkIdFetchRequest class allows a client to asynchronously
    request a list of landmark identifiers from a landmark manager.

    For a QLandmarkIdFetchRequest, the resultsAvailable() signal will be emitted when the resultant
    identifiers (which may be retrieved by calling landmarkIds()), are updated, as well as if
    the overall operation error (which may be retrieved by calling error()) is updated.

    Please see the class documentation for QLandmarkAbstractRequest for more information about
    the usage of request classes and ownership semantics.
