Hy...I try to explain better my question... Im using boost serialization text archive before sending data over TCP connection... Now I need to pass the received data to a Java application...so I would know if the serialized stream is composed only by the data or by the data + boost serialization(tag, code, etc.)... In this case my only chance to transfer the data to the java application, is to filter them before transfering?thanks...

I'll try to answer the question - but I'm sort of speculating as to what you want to do. I throw in some miscellanous observations which may or may not be helpful. a) Generally I don't suggest that one tries to use boost serialization to export data to non C++ applications. The library is intended to provide the easiest to use and most efficient implementation of serialization for C++ environments. Any ability to use this to export data to/from other environments is a coincidence. b) There are other tools for accomplishing the above. There is google protocol buffers and there is boost spirit/karma/qi which handle data in a way that is not connected to C++. Of course they won't be as automatic as serialization for just this reason. c) Never the less, some people have been able to do this. In large part it consists of not using those parts of the library which are strongly dependent C++ such as serialization of pointers. A useful place to start is one of the examples included with the package which creates a write only archive which can export any data which includes serialization functions. The leverages the serialization functions to save a lot of work at the expense of being to read the archive back. Something like might work for you. d) there are other examples around for serializing files with JSON and YAML formats. Again, these would likely mean not using some of the features of the serialization library - which might be be fine for you app. I realize this might not be much comfort - but hope it helps anyway.
