Hi Rafa,
I'm just merging your changes but feel that we need to add some
doxygen comments to clarify what the set*Iterator(..) and start(..)
methods relate to. My first bash at these comments follows:
/// set an input iterator, used directly when not using
InputStream with a traditional file releated stream.
void setInputIterator( InputIterator* ii ) { _in = ii; }
/// start reading from InputStream treating it as a traditional
file releated stream, handles headers and versioning
ReadType start( InputIterator* );
And
/// set an output iterator, used directly when not using
OutputStream with a traditional file releated stream.
void setOutputIterator( OutputIterator* oi ) { _out = oi; }
/// start writing to OutputStream treating it as a traditional
file releated stream, handles headers and versioning
void start( OutputIterator* outIterator, WriteType type );
Does this make sense? Feel free to suggest better wording.
Cheers,
Robert.
