<div dir="ltr"><div>My own opinion is that the use of these operators results in obfuscation. They were added to VTK waay back when VTK objects were passed by reference rather than by pointer, and back then one could write "matrix[i][j]". In comparison, (*matrix)[i][j] is hard to read. When I deprecated operator[], only one class in all of VTK was using it, so it definitely wasn't winning any popularity contests :)</div><div><br></div><div> - David</div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Sep 8, 2016 at 12:08 PM, Bob Obara <span dir="ltr"><<a href="mailto:bob.obara@kitware.com" target="_blank">bob.obara@kitware.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word">Hi David,<div><br></div><div>Thanks - what is the reason these interfaces are being deprecated?</div><span class="HOEnZb"><font color="#888888"><div><br></div><div>Bob</div></font></span><div><span class=""><br><div>
