// This implementation allows to increase performance
// of outputting data into a string
// avoiding reallocation of buffer.
//
// class LDOM_OSStream implements output into a sequence of
// strings and getting the result as a string.
// It inherits Standard_OStream (ostream).
// Beside methods of ostream, it also has additional
// useful methods: str(), Length() and Clear().
//
// struct LDOM_StringElem is one element of internal sequence
//
// class LDOM_SBuffer inherits streambuf and
// redefines some virtual methods of it
// (overflow() and xsputn())
// This class contains pointers on first
// and current element of sequence,
// also it has methods for the sequence management.
