From 3f2de87340b1c831ea59e4a3ca960d49f343c9fd Mon Sep 17 00:00:00 2001 From: Richard Linden Date: Mon, 17 Jun 2013 01:18:21 -0700 Subject: SH-3931 WIP Interesting: Add graphs to visualize scene load metrics added getAs and setAs to LLUnit to make it clearer how you specify units removed accidental 0-based indexing of periodicRecording history... should now be consistently 1-based, with 0 accessing current active recording removed per frame timer updates of all historical timer bars in fast timer display added missing assignment operator to recordings --- indra/llcommon/llunit.h | 182 +++++++++++++++++++++++------------------------- 1 file changed, 88 insertions(+), 94 deletions(-) (limited to 'indra/llcommon/llunit.h') diff --git a/indra/llcommon/llunit.h b/indra/llcommon/llunit.h index 5b961c81f0..5229fe69d7 100644 --- a/indra/llcommon/llunit.h +++ b/indra/llcommon/llunit.h @@ -30,31 +30,7 @@ #include "stdtypes.h" #include "llpreprocessor.h" #include "llerrorlegacy.h" - -namespace LLUnits -{ - -template -struct Convert -{ - static VALUE_TYPE get(VALUE_TYPE val) - { - // spurious use of dependent type to stop gcc from triggering the static assertion before instantiating the template - llstatic_assert_template(DERIVED_UNITS_TAG, false, "Cannot convert between types.");
