#define BL_BUFFER_5_HPP
//-------------------------------------------------------------------
// FILE: blBuffer_5.hpp
// CLASS: blBuffer_5
// BASE CLASS: blBuffer_4
//
//
//
// PURPOSE: -- This class is based on blBuffer_4 and adds
// circular ROI random access functions as well
// as iterators for the Region Of Interest (m_roi)
//
// -- The ROI iterators introduced in this class
// allow the user of this buffer to iterate over
// the buffer's ROI as if it was its own buffer.
//
// -- The ROI iterators are circular and allow a
// specified maximum number of circulations before
// reached the "end" ROI iterator
//
// -- This class is defined within the blBufferLIB
// namespace
//
