Detailed Description

CpuProfile contains a CPU profile in a form of top-down call tree (from main() down to functions that do all the work).

Member Function Documentation

◆ Delete()

void v8::CpuProfile::Delete ( )

Deletes the profile and removes it from CpuProfiler's list. All pointers to nodes previously returned become invalid.

◆ GetEndTime()

int64_t v8::CpuProfile::GetEndTime ( ) const

Returns time when the profile recording was stopped (in microseconds) since some unspecified starting point. The point is equal to the starting point used by GetStartTime.

◆ GetSample()

const CpuProfileNode * v8::CpuProfile::GetSample ( int index ) const

Returns profile node corresponding to the top frame the sample at the given index.

◆ GetSampleEmbedderState()

EmbedderStateTag v8::CpuProfile::GetSampleEmbedderState ( int index ) const

Returns state of the embedder when sample was captured.

◆ GetSamplesCount()

int v8::CpuProfile::GetSamplesCount ( ) const

Returns number of samples recorded. The samples are not recorded unless |record_samples| parameter of CpuProfiler::StartCpuProfiling is true.

◆ GetSampleState()

StateTag v8::CpuProfile::GetSampleState ( int index ) const

Returns state of the vm when sample was captured.

◆ GetSampleTimestamp()

int64_t v8::CpuProfile::GetSampleTimestamp ( int index ) const

Returns the timestamp of the sample. The timestamp is the number of microseconds since some unspecified starting point. The point is equal to the starting point used by GetStartTime.

◆ GetStartTime()

int64_t v8::CpuProfile::GetStartTime ( ) const

Returns time when the profile recording was started (in microseconds) since some unspecified starting point.

◆ GetTitle()

Local< String > v8::CpuProfile::GetTitle ( ) const

Returns CPU profile title.

◆ GetTopDownRoot()

const CpuProfileNode * v8::CpuProfile::GetTopDownRoot ( ) const

Returns the root node of the top down call tree.

◆ Serialize()

void v8::CpuProfile::Serialize	(	OutputStream *	stream,
		SerializationFormat	format = `kJSON`
	)		const

Prepare a serialized representation of the profile. The result is written into the stream provided in chunks of specified size.

For the JSON format, heap contents are represented as an object with the following structure:

{ nodes: [nodes array], startTime: number, endTime: number samples: [strings array] timeDeltas: [numbers array] }

The documentation for this class was generated from the following file:
