Detailed Description

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

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.

See also QMessageManager and QMessageFolder.

Member Function Documentation

QMessageFolderFilter::QMessageFolderFilter ()

See also QMessageFolder::id().

QMessageFolderFilter QMessageFolderFilter::byId ( const QMessageFolderFilter & filter, QMessageDataComparator::InclusionComparator cmp = QMessageDataComparator::Includes ) [static]

Returns a filter matching folders whose identifier is a member of the set yielded by filter, according to cmp.

This function was introduced in Qt Mobility 1.0.

See also QMessageFolder::id().

QMessageFolderFilter QMessageFolderFilter::byName ( const QString & pattern, QMessageDataComparator::LikeComparator cmp ) [static]

Returns a filter matching folders whose display name matches pattern, according to cmp.

This filter is evaluated when it is constructed.

This function was introduced in Qt Mobility 1.2.

See also QMessageFolder::name().

QMessageFolderFilter QMessageFolderFilter::byName ( const QString & value, QMessageDataComparator::EqualityComparator cmp ) [static]

Returns a filter matching folders whose display name matches value, according to cmp.

Not supported on Linux, Harmattan and Meego.com (use InclusionComparator).

This function was introduced in Qt Mobility 1.0.

See also QMessageFolder::name().

QMessageFolderFilter QMessageFolderFilter::byName ( const QString & value, QMessageDataComparator::InclusionComparator cmp = QMessageDataComparator::Includes ) [static]

Returns a filter matching folders whose display name matches the substring value, according to cmp.

This function was introduced in Qt Mobility 1.0.

See also QMessageFolder::name().

QMessageFolderFilter QMessageFolderFilter::byParentAccountId ( const QMessageAccountId & id, QMessageDataComparator::EqualityComparator cmp = QMessageDataComparator::Equal ) [static]

Returns a filter matching folders whose parent account identifier matches id, according to cmp.

This function was introduced in Qt Mobility 1.0.

See also QMessageAccount::id().

QMessageFolderFilter QMessageFolderFilter::byParentAccountId ( const QMessageAccountFilter & filter, QMessageDataComparator::InclusionComparator cmp = QMessageDataComparator::Includes ) [static]

Returns a filter matching folders whose parent account identifier is a member of the set yielded by filter, according to cmp.

This function was introduced in Qt Mobility 1.0.

See also QMessageAccount::id().

QMessageFolderFilter QMessageFolderFilter::byParentFolderId ( const QMessageFolderId & id, QMessageDataComparator::EqualityComparator cmp = QMessageDataComparator::Equal ) [static]

Returns a filter matching folders whose parent folder identifier matches id, according to cmp.

This function was introduced in Qt Mobility 1.0.

See also QMessageFolder::id().

QMessageFolderFilter QMessageFolderFilter::byParentFolderId ( const QMessageFolderFilter & filter, QMessageDataComparator::InclusionComparator cmp = QMessageDataComparator::Includes ) [static]

Returns a filter matching folders whose parent folder identifier is a member of the set yielded by filter, according to cmp.

This function was introduced in Qt Mobility 1.0.

See also QMessageFolder::id().

QMessageFolderFilter QMessageFolderFilter::byPath ( const QString & pattern, QMessageDataComparator::LikeComparator cmp ) [static]

Returns a filter matching folders whose path matches pattern, according to cmp.

This filter is evaluated when it is constructed.

This function was introduced in Qt Mobility 1.2.

See also QMessageFolder::path().

QMessageFolderFilter QMessageFolderFilter::byPath ( const QString & value, QMessageDataComparator::EqualityComparator cmp ) [static]

Returns a filter matching folders whose path matches value, according to cmp.

Not supported on Linux, Harmattan and Meego.com (use InclusionComparator).

This function was introduced in Qt Mobility 1.0.

See also QMessageFolder::path().

QMessageFolderFilter QMessageFolderFilter::byPath ( const QString & value, QMessageDataComparator::InclusionComparator cmp = QMessageDataComparator::Includes ) [static]

Returns a filter matching folders whose path matches the substring value, according to cmp.

This function was introduced in Qt Mobility 1.0.

See also QMessageFolder::path().

bool 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.

This function was introduced in Qt Mobility 1.0.

bool QMessageFolderFilter::isSupported () const

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

This function was introduced in Qt Mobility 1.0.

QMessageDataComparator::MatchFlags QMessageFolderFilter::matchFlags () const

Return the match flags for the search filter.

Default is no match flags set.

This function was introduced in Qt Mobility 1.0.

See also setMatchFlags().

void QMessageFolderFilter::setMatchFlags ( QMessageDataComparator::MatchFlags matchFlags )

This function was introduced in Qt Mobility 1.0.

See also matchFlags().

QMessageFolderFilter QMessageFolderFilter::operator& ( const QMessageFolderFilter & other ) const

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

This function was introduced in Qt Mobility 1.0.

const QMessageFolderFilter & QMessageFolderFilter::operator&= ( const QMessageFolderFilter & other )

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

This function was introduced in Qt Mobility 1.0.

QMessageFolderFilter QMessageFolderFilter::operator| ( const QMessageFolderFilter & other ) const

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

This function was introduced in Qt Mobility 1.0.

const QMessageFolderFilter & QMessageFolderFilter::operator|= ( const QMessageFolderFilter & other )

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

This function was introduced in Qt Mobility 1.0.

QMessageFolderFilter 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.

This function was introduced in Qt Mobility 1.0.
