    \class QMessageFolderFilter

    \brief The QMessageFolderFilter class defines the parameters used for querying a subset of
    all available folders from the messaging store.

    \inmodule QtMessaging

    \ingroup messaging
    \since 1.0

    A QMessageFolderFilter is composed of a folder property, an optional comparison operator
    and a comparison value. The QMessageFolderFilter class is used in conjunction with the
    QMessageManager::queryFolders() and QMessageManager::countFolders() functions to filter results
    which meet the criteria defined by the filter.

    QMessageFolderFilters can be combined using the logical operators (&), (|) and (~) to
    create more refined queries.

    Evaluation of filters is delayed until they are used in a QMessageManager function
    such as queryFolders, except where explicitly documented otherwise.

    \sa QMessageManager, QMessageFolder
*/

/*!
    \fn QMessageFolderFilter::QMessageFolderFilter()

    Creates a QMessageFolderFilter without specifying matching parameters.

    A default-constructed filter (one for which isEmpty() returns true) matches all folders.

    \sa isEmpty()

/*!
    \fn QMessageFolderFilter::QMessageFolderFilter(const QMessageFolderFilter &other)

    Constructs a copy of \a other.

    \fn QMessageFolderFilter::~QMessageFolderFilter()

    Destroys the filter.

    \fn QMessageFolderFilter::setMatchFlags(QMessageDataComparator::MatchFlags matchFlags)

    Set the match flags for the search filter to \a matchFlags.

    \since 1.0
    \sa matchFlags()
*/

/*!
    \fn QMessageDataComparator::MatchFlags QMessageFolderFilter::matchFlags() const

    Return the match flags for the search filter.

*/

/*!
    \fn QMessageFolderFilter::isEmpty() const

    Returns true if the filter remains empty after default construction; otherwise returns false.

    An empty filter matches all folders.

    The result of combining an empty filter with a non-empty filter using an AND operation is the
    original non-empty filter.

    The result of combining an empty filter with a non-empty filter using an OR operation is the
    empty filter.

    The result of combining two empty filters is an empty filter.

    \fn QMessageFolderFilter::operator~() const

    Returns a filter that is the logical NOT of the value of this filter (ignoring any
    matchFlags() set on the filter).

    If this filter is empty, the result will be a non-matching filter; if this filter is
    non-matching, the result will be an empty filter.
