Classes
class	AL::usdmaya::ProfilerSectionPath
	This class represents a path made up of AL::usdmaya::ProfilerSectionTag's. It is used so that we can distinguish between identical code sections, accessed from alternative paths, e.g. More...
class	AL::usdmaya::Profiler
	This class implements a very simple incode profiler. This profiler is NOT thread safe. It is mainly used to get some basic stats on the where the bottlenecks are during a file import/export operation. A simple example of usage: More...

Detailed Description

A series of classes and macros that provide a very simple in-code profiler to get some high level timings of the various processes during import / export operations.

Macro Definition Documentation

#define AL_BEGIN_PROFILE_SECTION

(

TimedSection

)

Value:

{ \
    static const AL::usdmaya::ProfilerSectionTag __entry(#TimedSection, __FILE__, __LINE__); \
    AL::usdmaya::Profiler::pushTime(&__entry); \
  }

Put this macro at the start of a timed section of code

#define AL_END_PROFILE_SECTION

(

)

{ AL::usdmaya::Profiler::popTime(); }

Put this macro after a timed section of code.

Variable Documentation

const uint32_t AL::usdmaya::MAX_TIMESTAMP_STACK_SIZE = 16

a constant that determines the maximum possible depth of the timing
