示例1: similarTo
// ** Films::similarTo
SimilarFilmsArray Films::similarTo( const std::string& oid, int count ) const
{
SimilarFilmsArray result;
OID objectId = OID( oid );
CollectionPtr similars = m_target->collection( "similar" );
CursorPtr cursor = similars->find( QUERY( "$or" << ARRAY( DOCUMENT( "first" << oid ) << DOCUMENT( "second" << objectId ) ) ) );
DocumentPtr document;
while( (document = cursor->next()) ) {
// ** Read data from document
OID first = document->objectId( "first" );
OID second = document->objectId( "second" );
int value = document->integer( "value" );
// ** Decode similarity & accuracy
float similarity, accuracy;
decodeSimilarity( value, similarity, accuracy );
// ** Push similar film
Film film = filmById( first == objectId ? second : first );
Quality quality = qualityFromRange( similarity, m_similarityQuartiles );
result.push_back( SimilarFilm( film, similarity, accuracy, quality ) );
}
std::sort( result.begin(), result.end(), SimilarFilm::sortBySimilarity );
if( count ) {
result.resize( std::min( count, ( int )result.size() ) );
}
return result;
