Detailed Description

The QGalleryIntersectionFilter class provides a filter which matches the intersection of two or more meta-data filters.

An intersection filter represents the intersection of a list of gallery filters. Filters can be added to an intersection using either the append(), prepend(), or insert() functions, or using the << operator.

Intersection filters can also combining two gallery filters with the && operator.

QGalleryIntersectionFilter::QGalleryIntersectionFilter ()

Constructs an empty intersection.

This function was introduced in Qt Mobility 1.1.

Constructs a copy of an intersection filter.

This function was introduced in Qt Mobility 1.1.

QGalleryIntersectionFilter::~QGalleryIntersectionFilter ()

Destroys an intersection filter.

void QGalleryIntersectionFilter::append ( const QGalleryMetaDataFilter & filter )

Appends a meta-data filter to an intersection.

This function was introduced in Qt Mobility 1.1.

void QGalleryIntersectionFilter::append ( const QGalleryUnionFilter & filter )

Appens a union filter to an intersection.

This function was introduced in Qt Mobility 1.1.

void QGalleryIntersectionFilter::append ( const QGalleryIntersectionFilter & filter )

Appends the contents of an intersection filter to an intersection.

This function was introduced in Qt Mobility 1.1.

void QGalleryIntersectionFilter::clear ()

Clears all the filters from an intersection.

This function was introduced in Qt Mobility 1.1.

int QGalleryIntersectionFilter::filterCount () const

Returns the number of filters in an intersection.

This function was introduced in Qt Mobility 1.1.

QList<QGalleryFilter> QGalleryIntersectionFilter::filters () const

Return the filters contained in an intersection.

This function was introduced in Qt Mobility 1.1.

void QGalleryIntersectionFilter::insert ( int index, const QGalleryMetaDataFilter & filter )

Inserts a meta-data filter into an intersection at index.

void QGalleryIntersectionFilter::insert ( int index, const QGalleryUnionFilter & filter )

Inserts a union filter into an intersection at index.

This function was introduced in Qt Mobility 1.1.

void QGalleryIntersectionFilter::insert ( int index, const QGalleryIntersectionFilter & filter )

Inserts the contents of an intersection filter into an intersection at index.

This function was introduced in Qt Mobility 1.1.

bool QGalleryIntersectionFilter::isEmpty () const

Returns true if an intersection does not contain any filters, and returns false otherwise.

This function was introduced in Qt Mobility 1.1.

Replaces the filter at index in an intersection with a meta-data filter.

This function was introduced in Qt Mobility 1.1.

void QGalleryIntersectionFilter::replace ( int index, const QGalleryUnionFilter & filter )

Replaces the filter at index in an intersection with a union filter.

This function was introduced in Qt Mobility 1.1.
