One of these is maintained + * for each region encountered and the 'current' region is available + * as a simple reference. Each thread (presently two) interested + * in participating in these stats gets an instance of the + * LLViewerAssetStats class so that threads are completely + * independent. + * + * The idea of a current region is used for simplicity and speed + * of categorization. Each metrics event could have taken a + * region uuid argument resulting in a suitable lookup. Arguments + * against this design include: + * + * - Region uuid not trivially available to caller. + * - Cost (cpu, disruption in real work flow) too high. + * - Additional precision not really meaningful. + * + * By itself, the LLViewerAssetStats class is thread- and + * viewer-agnostic and can be used anywhere without assumptions + * of global pointers and other context. For the viewer, + * a set of free functions are provided in the namespace + * LLViewerAssetStatsFF which *do* implement viewer-native + * policies about per-thread globals and will do correct + * defensive tests of same. + * + * References + * + * Project: + * <TBD> + * + * Test Plan: + * <TBD> + * + * Jiras: + * <TBD> + * + * Unit Tests: + * indra/newview/tests/llviewerassetstats_test.cpp + * + */ + + +// ------------------------------------------------------ +// Global data definitions +// ------------------------------------------------------ +LLViewerAssetStats * gViewerAssetStatsMain(0);
