Comments for C++ Portable Types Library (PTypes)

Very Nice Library!
In the time it took me to get Boost and ACE* compiled and usable as plugin libraries I was able to make a controlled document webserver application complete with view/update/tracking/collaboration capabilities using PTypes library that works in a diverse network environment for proof of concept.

This is definitely a library that will be a main stay in my own personal toolbox!

*I am not being critical of Boost, ACE, or STL as I have used them extensively and they are great libraries. My point is PTypes is one of the first truly plug it and go with code bases I have come across in a long time with such a gentle learning curve/functionality ratio. Awesome library.

I did some tests on my FreeBSD and also on a Windows 2003 machine with MSVC. In summary, the basic operations on dynamic arrays (std::vector and pt::tpodlist) are nearly equal, but PTypes produces less binary code.

The picture with dynamic strings is different. PTypes performs better than Microsoft's string class, but it is worse than GNU.

As for memory usage, PTypes uses less memory space for strings compared to GNU, by exactly one 'int' per string (the capacity is not stored, a quantization algorithm is used instead in PTypes).

(BTW, a better place to discuss this is the project management page at SourceForge.net:

PTypes / STL comparative


Has somebody done a comparative between PTypes and STL? It should be nice to see a comparative about performance and memory ocupation for several hungry-resource problems.
