  class Buffer
A very simple buffer class that allocates a buffer of a given type and size in the constructor and deallocates the buffer in the destructor. This class is useful everywhere where a temporary buffer is needed. { public: Buffer(std::size_t size): _size(size), _ptr(new T[size]) Creates and allocates the Buffer. { } ~Buffer() Destroys the Buffer. { delete [] _ptr; } std::size_t size() const Returns the size of the buffer. { return _size; } T* begin() Returns a pointer to the beginning of the buffer. { return _ptr; } const T* begin() const Returns a pointer to the beginning of the buffer. { return _ptr; } 

          T* end()
Returns a pointer to end of the buffer. { return _ptr + _size; } const T* end() const Returns a pointer to the end of the buffer. { return _ptr + _size; } T& operator [] (std::size_t index) { poco_assert (index < _size); return _ptr[.]; } 

          const T& operator [] (std::size_t index) const
          {
                  poco_assert (index < _size);
                  
                  return _ptr[index];
          }
