A basic_iostream class that holds a character vector specified by CharVector template parameter as its formatting buffer. The vector must have contiguous storage, like std::vector, boost::interprocess::vector or boost::interprocess::basic_string
basic_vectorstream
public
construct/copy/destructbasic_vectorstream(std::ios_base::openmode mode = std::ios_base::in|std::ios_base::out);
Constructor. Throws if vector_type default constructor throws.
template<typename VectorParameter> basic_vectorstream(const VectorParameter & param, std::ios_base::openmode mode = std::ios_base::in|std::ios_base::out);
Constructor. Throws if vector_type(const VectorParameter ¶m) throws.

void swap_vector(vector_type & vect);
Swaps the underlying vector with the passed vector. This function resets the read/write position in the stream. Does not throw.
const vector_type & vector() const;
Returns a const reference to the internal vector. Does not throw.
void reserve(typename vector_type::size_type size);
Calls reserve() method of the internal vector. Resets the stream to the first position. Throws if the internals vector's reserve throws.
void clear();
Calls clear() method of the internal vector. Resets the stream to the first position.
