Constructor & Destructor Documentation

CpuProfilingOptions() [1/2]

v8::CpuProfilingOptions::CpuProfilingOptions	(	CpuProfilingMode	mode = kLeafNodeLineNumbers,
		unsigned	max_samples = kNoSampleLimit,
		int	sampling_interval_us = 0,
		MaybeLocal< Context >	filter_context = MaybeLocal<Context>() )

Parameters

mode	Type of computation of stack frame line numbers.
max_samples	The maximum number of samples that should be recorded by the profiler. Samples obtained after this limit will be discarded.
sampling_interval_us	controls the profile-specific target sampling interval. The provided sampling interval will be snapped to the next lowest non-zero multiple of the profiler's sampling interval, set via SetSamplingInterval(). If zero, the sampling interval will be equal to the profiler's sampling interval.
filter_context	If specified, profiles will only contain frames using this context. Other frames will be elided.
