override

Start profiling the given engine.

If engine is 0, start all engine profilers that aren't currently running.

If any engine profiler is started like that also start all global profilers.

Here is the caller graph for this function:

◆ stopProfiling()

void QQmlProfilerServiceImpl::stopProfiling ( QJSEngine * engine)
override

Stop profiling the given engine.

If engine is 0, stop all currently running engine profilers.

If afterwards no more engine profilers are running, also stop all global profilers. Otherwise only make them report their data.
