    \class QMessageId

    \ingroup messaging

    \brief The QMessageId class provides a unique identifier for a QMessage message within the 

    scope of the messaging store.

    A QMessageId can be constructed from a string, or converted to a string with toString().

    A QMessageId instance can be tested for validity with isValid(), and compared to other instances

    for equality.

    If the message a QMessageId identifies is removed from the messaging store then the identifier 

    will not be reused.

    The QMessageId implementation should be as small as is practical for the underlying platform.

    \sa QMessage, QMessageManager

*/

/*!

    \fn QMessageId::QMessageId()

    Creates an invalid identifier, toString() will return a null string.

*/

/*!

    \fn QMessageId::QMessageId(const QMessageId& other)

    Constructs a copy of \a other.

*/

/*!

    \fn QMessageId::QMessageId(const QString& id)

    Constructs an identifier from \a id.

    \sa toString()

    \fn QMessageId::~QMessageId()

    \fn bool QMessageId::operator<(const QMessageId &other) const

*/

/*!

    \fn bool QMessageId::toString() const

    Returns the string representation of this identifier.

    A null string should be returned if and only if the identifier is invalid.

    String representations of identifiers should not be used to test for equality, instead 

    the equality operator should be used.
