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.

QGalleryIntersectionFilter::QGalleryIntersectionFilter ( const QGalleryMetaDataFilter & filter )

Constructs an intersection filter from a meta-data filter.

This function was introduced in Qt Mobility 1.1.

QGalleryIntersectionFilter::QGalleryIntersectionFilter ( const QGalleryUnionFilter & filter )

Constructs an intersection filter from a union filter.

This function was introduced in Qt Mobility 1.1.

QGalleryIntersectionFilter::QGalleryIntersectionFilter ( const QGalleryIntersectionFilter & filter )

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.

This function was introduced in Qt Mobility 1.1.

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.

bool QGalleryIntersectionFilter::isValid () const

Returns true if the filter is a valid intersection filter.

An invalid filter can be obtained by casting a non QGalleryFilter::Intersection type QGalleryFilter to QGalleryIntersectionFilter.

void QGalleryIntersectionFilter::prepend ( const QGalleryIntersectionFilter & filter )

Prepends the contents of an intersection filter to an intersection.

This function was introduced in Qt Mobility 1.1.

void QGalleryIntersectionFilter::remove ( int index )

This function was introduced in Qt Mobility 1.1.

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

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.

This function was introduced in Qt Mobility 1.1.

QGalleryIntersectionFilter & QGalleryIntersectionFilter::operator= ( const QGalleryIntersectionFilter & filter )

Assigns the value of filter to another intersection filter.

This function was introduced in Qt Mobility 1.1.
