Re: [Pythoncad-developer] Test Performance

[Matteo B. <mat...@bo...>]

I did the test and lookign at this function
def getEntityFromTypeArray(self, typeArray):
        """
            get entitys from an array of type
        """
        _outObj=[]
        _dbEntRow=self.getMultiFilteredEntity(entityTypeArray=typeArray)

-->> here we have 31 Mb  and all the entity are in the _dbEntRow

        for _row in _dbEntRow: 
            _style=_row[4]
            _dumpObj=pickle.loads(str(_row[3]))
            _objEnt=PyCadEnt(_row[2],_dumpObj,_style,_row[1])
            _objEnt.state=_row[5]
            _objEnt.index=_row[6]
            _objEnt.visible=_row[7]
            _objEnt.updateBBox()            
            _outObj.append(_objEnt)
        return _outObj            

--> here we have 400 Mb approximatively

Matteo
