The template class describes an object that controls extraction of elements and encoded objects from a stream buffer
of class basic_stringbuf
<E, T, A>
, with elements of type E
, whose character traits are determined by the class T
,
and whose elements are allocated by an allocator of class A
. The object stores an object of class
basic_stringbuf<E, T, A>
.
