Member Function Documentation

void Delete ( )

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

int64_t 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.

const CpuProfileNode* GetSample ( int  index) const

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

int GetSamplesCount ( ) const

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

int64_t 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.

int64_t GetStartTime ( ) const

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

Handle<String> GetTitle ( ) const

Returns CPU profile title.

const CpuProfileNode* GetTopDownRoot ( ) const

Returns the root node of the top down call tree.
