  PyBuffer getBuffer​(int flags)
              throws PyException

  Method by which the consumer requests the buffer from the exporter. The consumer provides information on its intended method of navigation and the features the buffer object is asked (or assumed) to provide. Each consumer requesting a buffer in this way, when it has finished using it, should make a corresponding call to PyBuffer.release() on the buffer it obtained, since some objects alter their behaviour while buffers are exported.

  Parameters:

  flags - specifying features demanded and the navigational capabilities of the consumer

  Returns:

  exported buffer

  Throws:

  PyException - (BufferError) when expectations do not correspond with the buffer
