This class enables the implementation of string-stream types by providing a trivial type containing a basic_stringbuf that is suitable as a (private) base class for a string-stream. Inheriting from StringBufContainer allows the string-stream to ensure that the contained basic_stringbuf is initialized before initializing other base classes or data members without potentially overriding virtual methods in the basic_stringbuf type. Note that implementations of string-stream types must pass the address of a string-buffer to their public base class (e.g., basic_stream ), so the string-stream must ensure (using private inheritance) that the string-buffer is initialized before constructing the public base class. If a string-stream implementation were to directly inherit from basic_streambuf , then virtual methods defined in that string-stream (e.g., underflow) might incorrectly override those in the basic_stringbuf implementation.
