explicit basic_stringbuf(
ios_base::openmode which = ios_base::in | ios_base::out);
Effects:
Constructs an object of class
basic_stringbuf,
initializing the base class with
basic_streambuf() (
[streambuf.cons]), and initializing
mode
with
which. Postconditions:
str() == "". explicit basic_stringbuf(
const basic_string<charT, traits, Allocator>& s,
ios_base::openmode which = ios_base::in | ios_base::out);
Effects:
Constructs an object of class
basic_stringbuf,
initializing the base class with
basic_streambuf() (
[streambuf.cons]), and initializing
mode
with
which. basic_stringbuf(basic_stringbuf&& rhs);
Effects: Move constructs from the rvalue
rhs. It
is
implementation-defined whether the sequence pointers in
*this
(
eback(),
gptr(),
egptr(),
pbase(),
pptr(),
epptr()) obtain
the values which
rhs had
. Whether they do or not,
*this
and
rhs reference separate buffers (if any at all) after the
construction
. The openmode, locale and any other state of
rhs is
also copied
.Postconditions: Let
rhs_p refer to the state of
rhs just prior to this construction and let
rhs_a
refer to the state of
rhs just after this construction
. str() == rhs_p.str()

egptr() - eback() == rhs_p.egptr() - rhs_p.eback()
