XTL is a library of template classes and functions for reading/writing
|
|
structured data to/from an external (platform independent) representation.
|
|
This process is also usually known as marshalling, serialization or pickling,
|
|
and is useful both for heterogeneous network programming and portable
|
|
persistent storage.
|
|
|
|
Currently, XTL supports XDR (Internet standard), GIOP CDR (CORBA standard)
|
|
and readable ascii text (write-only) as data formats. Memory buffers and C++
|
|
iostreams are usable as data sources/targets. Besides the usual C data types
|
|
(basic, structs, pointers, unions), the XTL also supports C++ constructs,
|
|
such as pointers to base classes and template types, namely, STL containers.
|
|
|
|
XTL does not include any kind of IDL, and as such, the programmer is required
|
|
to write a "filter" for each data type. The API is somewhat modeled on the
|
|
original XDR library by Sun, in that the same filter is used for both reading
|
|
and writing. However, heavy usage of templates makes the API simpler and type
|
|
safe. Function inlining and careful avoidance of pointers or virtual
|
|
functions, also make generated code faster.
