/**
|
|
* nsITimelineService is used to constuct a timeline of program
|
|
* execution. The timeline is output to a file, either stderr or the
|
|
* value of the environment variable NS_TIMELINE_LOG_FILE. On the
|
|
* Mac, the timeline is output to the file named "timeline.txt". The
|
|
* reason it's different on the Mac is that the Mac environment
|
|
* initialization code happens after timeline initialization code.
|
|
*
|
|
* If NS_TIMELINE_INIT_TIME is set in the environment, that will be
|
|
* used as the time of startup; otherwise the current time when mark()
|
|
* is first called will be used.
|
|
*
|
|
* mark() is used to put marks on the timeline.
|
|
*
|
|
* indent() and outdent() are used to format the timeline a bit to
|
|
* show nesting. This doesn't produce perfect results in the face of
|
|
* asychrony and multiple threads.
|
|
*
|
|
* enter() and leave() are convenience functions that add marks to the
|
|
* timeline and do indentation.
|
|
*
|
|
* startTimer() and stopTimer() control named stop watches. If
|
|
* startTimer() is called more than once, an equal number of
|
|
* stopTimer() calls are needed to actually stop the timer. This
|
|
* makes these timers slightly useful in a threaded environment.
|
|
*
|
|
* markTimer() puts a mark on the timeline containing the total for
|
|
* the named timer.
|
|
*
|
|
* Don't use nsITimelineService in C++ code; use the NS_TIMELINE
|
|
* macros instead. nsITimelineService exists so that JavaScript code
|
|
* can mark the timeline.
