[Seqan-dev] CharString question

[Raymond Wan <rwan@cuhk.edu.hk>]

Hi all,

Somewhat of a basic question, but I haven't been able to figure it out.

How does one take a substring (and if possible, prefix or suffix) of a
CharString?

And how does one find out the length of a CharString?

And can someone tell me the reasoning for creating CharString type in SeqAn and
not just using (or extending) C++'s <string>?  Likewise, I've noticed
functions, etc. that is also done by other libraries -- Boost is the one that
comes to mind.  I can't think of examples at the moment, but was there any
reason for duplicating such effort?  Was it to not rely on other non-standard
libraries?

Thank you!

Ray
