Re: Re: Improving speed (long)

Hi Lukas, > Well ideally the user does not have to choose anything but only use what > method he/she pleases Exactly, so you make the default class that the object factory creates the MySQL_Extended class -- this gives you everything. If you want low-level high speed access and do not want any overhead, tell the object factory that you want the low-level version, eg: MySQL_Primitives_Metabase. Just like you choose assembler for speed or PHP for productivity - give people a choice - they will applaud you. One size only fits yourself :-) Regards, John Lukas Smith <smith@dybnet.de> wrote in message news:001501c1cf6b$933467a0$4d00a8c0@vandal... > Well ideally the user does not have to choose anything but only use what > method he/she pleases.
