Constructor & Destructor Documentation

◆ CpuProfilingOptions()

CpuProfilingOptions ( CpuProfilingMode  mode = kLeafNodeLineNumbers,
unsigned  max_samples = kNoSampleLimit,
int  sampling_interval_us = 0,
MaybeLocal< Context filter_context = MaybeLocalContext >() 
modeType of computation of stack frame line numbers.
max_samplesThe maximum number of samples that should be recorded by the profiler. Samples obtained after this limit will be discarded.
sampling_interval_uscontrols 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.
