There is no "the serialization technique" ... there are many ways of implementing serialization. There are also many methods of data compression. What is it exactly that you want to do? And what does it have to do with the C++ language? -- Bob Hairgrove [email]NoSpamPlease (AT) Home (DOT) com[/email] Back to top Mike Wahler Guest Posted: Sat Dec 18, 2004 10:48 pm    Post subject: Re: Serialization and data compression methods "Alex Vinokur" <alexvn (AT) big-foot (DOT) com> wrote Quote: Are data compression methods used as the serialization technique? They are used as one possible serialization method by some applications, those that need it. Other applications use some other technique, depending upon their needs. E.g. If I serialize some text for purposes of transmitting to a printer, I certainly don't want to compress or 'encrypt' it. This isn't really a C++ question, but a design question, perhaps better addressed in e.g. comp.programming -Mike Back to top Mike Wahler Guest Posted: Sat Dec 18, 2004 10:49 pm    Post subject: Re: Serialization and data compression methods "Alex Vinokur" <alexvn (AT) big-foot (DOT) com> wrote Quote: "Rolf Magnus" <ramagnus (AT) t-online (DOT) de> wrote Alex Vinokur wrote: Are data compression methods used as the serialization technique? of what?

Yes and no. When data objects are big, or transmission time is costly, then data compression is applied. When 1200 Baud modems were the norm, everything was compressed to save transmission time. It is a time-memory trade off. You are trading memory size for compress and uncompress time. Only you and the users of your application can judge which is more important. -- Thomas Matthews C++ newsgroup welcome message: http://www.slack.net/~shiva/welcome.txt C++ Faq: http://www.parashift.com/c++-faq-lite C Faq: http://www.eskimo.com/~scs/c-faq/top.html alt.comp.lang.learn.c-c++ faq: http://www.comeaucomputing.com/learn/faq/ Other sites: http://www.josuttis.com -- C++ STL Library book http://www.sgi.com/tech/stl -- Standard Template Library Back to top Thomas Matthews Guest Posted: Sun Dec 19, 2004 2:42 am    Post subject: Re: Serialization and data compression methods Alex Vinokur wrote: Quote: "Rolf Magnus" <ramagnus (AT) t-online (DOT) de> wrote Alex Vinokur wrote: Are data compression methods used as the serialization technique? of what?

See also "cryptography." Many applications have been writing objects to the disk, tape, punched tape, etc., for many decades without encoding them. -- Thomas Matthews C++ newsgroup welcome message: http://www.slack.net/~shiva/welcome.txt C++ Faq: http://www.parashift.com/c++-faq-lite C Faq: http://www.eskimo.com/~scs/c-faq/top.html alt.comp.lang.learn.c-c++ faq: http://www.comeaucomputing.com/learn/faq/ Other sites: http://www.josuttis.com -- C++ STL Library book http://www.sgi.com/tech/stl -- Standard Template Library Back to top Jeff Flinn Guest Posted: Mon Dec 20, 2004 1:50 pm    Post subject: Re: Serialization and data compression methods Alex Vinokur wrote: Quote: Are data compression methods used as the serialization technique Not 'as' but 'with'. See the boost.serialization library and the upcoming boost.iostream library by Jonathan Turkanis. The serialization library is independent of stream type, and the iostream library provides the ability to easily create compressed streams.
