    \class QMessageFilter

    \brief The QMessageFilter class defines the parameters used for querying a subset of

    all available messages from the messaging store.

    \ingroup messaging

    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

    \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)

    Constructs a copy of \a other.

*/

/*!

    \fn QMessageFilter::~QMessageFilter()

    Destroys the filter.

    \internal

    \fn QMessageFilter& QMessageFilter::operator=(const QMessageFilter& other)

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

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

    \sa matchFlags()

*/

/*!

    \fn QMessageFilter::matchFlags() const

    Return the match flags for the search filter.

    Default is no match flags set.

    \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 is the original non-empty filter. 

    This is true regardless of whether the combination is formed by an AND or an OR operation.

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

*/

/*!

    \fn QMessageFilter::isSupported() const

    Returns true if the filter is supported on the current platform; otherwise returns false.

*/

/*!

    \fn QMessageFilter::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.

    \sa isEmpty()

*/

/*!

    \fn QMessageFilter::operator&(const QMessageFilter& other) const

    Returns a filter that is the logical AND of this filter and the value of filter \a other.

*/

    \fn QMessageFilter::operator|(const QMessageFilter& other) const

    Returns a filter that is the logical OR of this filter and the value of filter \a other.

*/

/*!

    \fn QMessageFilter::operator&=(const QMessageFilter& other)

    Performs a logical AND with this filter and the filter \a other and assigns the result

    to this filter.

    \fn QMessageFilter::operator|=(const QMessageFilter& other)

    Performs a logical OR with this filter and the filter \a other and assigns the result
