    \class QMessageFilter

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

    \inmodule QtMessaging

    \ingroup messaging
    \since 1.0

    A QMessageFilter is composed of a message property, an optional comparison operator
    and a comparison value. The QMessageFilter class is used in conjunction with the
    QMessageManager::queryMessages(), QMessageManager::countMessages(),
    QMessageService::queryMessages(), and QMessageService::countMessages()
    functions to filter results which meet the criteria defined by the filter.

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

    For example:

    To create a query for all messages sent from "joe@user.com" with subject "meeting":
    \code
    QMessageFilter subjectFilter(QMessageFilter::bySubject("meeting"));
    QMessageFilter senderFilter(QMessageFilter::bySender("joe@user.com"));
    QMessageIdList results = QMessageManager().queryMessages(subjectFilter & senderFilter);
    \endcode

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

    \sa QMessageManager, QMessage
*/

/*!
    \fn QMessageFilter::QMessageFilter()

    Creates a QMessageFilter without specifying matching parameters.

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

    \sa isEmpty()

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

*/

/*!
    \fn QMessageFilter::matchFlags() const

    Return the match flags for the search filter.

    \since 1.0
    \sa setMatchFlags()
*/

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

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

    An empty filter matches all messages.

    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 using either an AND or OR operation is an empty filter.

    Returns a filter that is the logical NOT of the value of this filter (ignoring any

    non-matching, the result will be an empty filter.
