/*!
    \class QLandmarkFetchByIdRequest
    \brief The QLandmarkFetchByIdRequest class allows a client to asynchronously
    request a list of landmarks by id from a landmark manager.

    For a QLandmarkFetchByIdRequest, the resultsAvailable() signal will be emitted when the resultant
    landmarks (which may be retrieved by calling landmarks()) are updated,
    whenever indiviual items error out(individual errors may be retrieved by
    calling errorMap()), or when an overall operation error occurs(which may be
    retrieved by calling error()).

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