Detailed Description
The QMessageFilter class defines the parameters used for querying a subset of all available messages from the messaging store.
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 QMessageStore::queryMessages (), QMessageStore::countMessages (), QMessageServiceAction::queryMessages (), and QMessageServiceAction::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":
QMessageFilter subjectFilter(QMessageFilter::bySubject("meeting"));
QMessageFilter senderFilter(QMessageFilter::bySender("joe@user.com"));
QMessageIdList results = QMessageStore::instance()->queryMessages(subjectFilter & senderFilter);

Member Function Documentation
QMessageFilter::QMessageFilter ()
Creates a QMessageFilter without specifying matching parameters.
A default-constructed filter (one for which isEmpty () returns true) matches all messages.
See also isEmpty ().
QMessageFilter::QMessageFilter ( const QMessageFilter & other )
Constructs a copy of other .
QMessageFilter::~QMessageFilter () [virtual]
Destroys the filter.
Returns a filter matching messages whose ancestor folders' identifiers contain id , according to cmp .
See also QMessage::parentFolderId ().
Returns a filter matching messages whose ancestor folders' identifiers contain a member of the set yielded by filter , according to cmp .
See also QMessage::parentFolderId ().
Returns a filter matching messages whose identifier matches id , according to cmp .
See also QMessage::id ().
QMessageFilter QMessageFilter::byId ( const QMessageIdList & ids , QMessageDataComparator::InclusionComparator cmp = QMessageDataComparator::Includes ) [static]
Returns a filter matching messages whose identifier is a member of ids , according to cmp .
See also QMessage::id ().
QMessageFilter QMessageFilter::byId ( const QMessageFilter & filter , QMessageDataComparator::InclusionComparator cmp = QMessageDataComparator::Includes ) [static]

See also QMessage::priority ().
QMessageFilter QMessageFilter::byReceptionTimeStamp ( const QDateTime & value , QMessageDataComparator::EqualityComparator cmp = QMessageDataComparator::Equal ) [static]
Returns a filter matching messages whose reception timestamp matches value , according to cmp .
See also QMessage::receivedDate ().
Returns a filter matching messages whose reception timestamp has the relation to value that is specified by cmp .
See also QMessage::receivedDate ().
QMessageFilter QMessageFilter::byRecipients ( const QString & value , QMessageDataComparator::InclusionComparator cmp = QMessageDataComparator::Includes ) [static]
Returns a filter matching messages whose recipients include the substring value , according to cmp .
See also QMessage::to (), QMessage::cc (), and QMessage::bcc ().
Returns a filter matching messages whose sender matches value , according to cmp .
See also QMessage::from ().
QMessageFilter QMessageFilter::bySender ( const QString & value , QMessageDataComparator::InclusionComparator cmp = QMessageDataComparator::Includes ) [static]
Returns a filter matching messages whose sender matches the substring value , according to cmp .
See also QMessage::from ().

Returns a filter matching messages whose status matches value , according to cmp .
See also QMessage::status ().
Returns a filter matching messages whose status is a bitwise match to mask , according to cmp .
See also QMessage::status ().
Returns a filter matching messages whose subject matches value , according to cmp .
See also QMessage::subject ().
QMessageFilter QMessageFilter::bySubject ( const QString & value , QMessageDataComparator::InclusionComparator cmp = QMessageDataComparator::Includes ) [static]
Returns a filter matching messages whose subject matches the substring value , according to cmp .
See also QMessage::subject ().
QMessageFilter QMessageFilter::byTimeStamp ( const QDateTime & value , QMessageDataComparator::EqualityComparator cmp = QMessageDataComparator::Equal ) [static]
Returns a filter matching messages whose timestamp matches value , according to cmp .
See also QMessage::date ().
Returns a filter matching messages whose timestamp has the relation to value that is specified by cmp .
See also QMessage::date ().
Returns a filter matching messages whose type matches type , according to cmp .
See also QMessage::type ().
Returns a filter matching accounts whose type is a bitwise match to type , according to cmp .
See also QMessage::type ().
bool 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.
bool QMessageFilter::isSupported () const
Returns true if the filter is supported on the current platform; otherwise returns false.
Return the options for the search filter.
Default is no options set.
See also setOptions ().
Set the options for the search filter to options .
See also options ().
QMessageFilter QMessageFilter::operator& ( const QMessageFilter & other ) const
Returns a filter that is the logical AND of this filter and the value of filter other .
const QMessageFilter & QMessageFilter::operator&= ( const QMessageFilter & other )
Performs a logical AND with this filter and the filter other and assigns the result to this filter.
QMessageFilter QMessageFilter::operator| ( const QMessageFilter & other ) const
Returns a filter that is the logical OR of this filter and the value of filter other .
const QMessageFilter & QMessageFilter::operator|= ( const QMessageFilter & other )
Performs a logical OR with this filter and the filter other and assigns the result to this filter.
QMessageFilter QMessageFilter::operator~ () const
Returns a filter that is the logical NOT of the value of this filter (ignoring any options () 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.
See also isEmpty ().
