// FILE: blBuffer_4.hpp
// CLASS: blBuffer_4
// BASE CLASS: blBuffer_3
//
//
//
// PURPOSE: -- This class is based on blBuffer_3 and adds
// a Region Of Interest (m_roi)
//
// -- For a ROI that does not span the entire buffer
// with coordinates (row1,col1,page1) to (row2,col2,page2)
// also known as (y1,x1,z1) to (y2,x2,z2)
// -- For a 1d-buffer the ROI is contiguous
// -- For 2d-buffer the ROI is made of (row2 - row1) separate
// contiguous pieces
// -- For 3d-buffer the ROI is made of (row2 - row1)*(page2 - page1)
// separate contiguous pieces
// -- And so on for higher nd-buffers
//
// -- This class is defined within the blBufferLIB
// namespace
//
