C++ (Cpp) BSONObj::extractFields Examples

Example #1

File: group.cpp Project: pombredanne/semi_index

 BSONObj getKey( const BSONObj& obj , const BSONObj& keyPattern , ScriptingFunction func , double avgSize , Scope * s ) {
     if ( func ) {
         BSONObjBuilder b( obj.objsize() + 32 );
         b.append( "0" , obj );
         int res = s->invoke( func , b.obj() );
         uassert( 10041 ,  (string)"invoke failed in $keyf: " + s->getError() , res == 0 );
         int type = s->type("return");
         uassert( 10042 ,  "return of $key has to be an object" , type == Object );
         return s->getObject( "return" );
     }
     return obj.extractFields( keyPattern , true );
 }

Example #2

File: d_chunk_manager.cpp Project: danpe91/mongo

    bool ShardChunkManager::belongsToMe( const BSONObj& obj ) const {
        if ( _rangesMap.size() == 0 )
            return false;

        return _belongsToMe( obj.extractFields( _key , true ) );
    }
