bool x_CheckValidity(const CTempString &err_msg) const

void Post(CRequestStatus::ECode status, CTempString status_msg=CTempString())

Write the collected resource info and timing to the log.

#define ERR_POST_ONCE(message)

Error posting only once during program execution.

EStart

If to start the timing immediately.

CDiagContext_Extra Post(CRequestStatus::ECode status, CTempString resource, CTempString status_msg=CTempString())

Log the timing; stop and deactivate the timer.

~CPerfLogger()

If the timer is still active, then post an error (once).

double GetElapsedTime(void) const

Get total elapsed time (including any adjustments) in seconds.

CPerfLogGuard(CTempString resource, CPerfLogger::EStart state=CPerfLogger::eStart)

Constructor.

void Discard(void)

Discard the results.

CPerfLogger & GetLogger(void)

Access logger directly.

void Discard(void)

Discard the timing results; stop and deactivate the timer.

SDiagMessage::TExtraArgs m_Parameters

list< TExtraArg > TExtraArgs

const CTime & GetLoggerStartTime(void) const

Get the logger's start time.

CPerfLogger(EStart state=eStart)

Constructor. Starts the timer by default.

void Adjust(CTimeSpan timespan)

Adjust the printed elapsed time.

pair< string, string > TExtraArg

static bool IsON(void)

Is performance logging on, globally? Controlled by CParam(section="Log", entry="PerfLogging",...

~CPerfLogGuard()

If Post() or Discard() have not been called, then log the collected info with status 500.

CStopWatch::EStart m_TimerState

void Suspend(void)

Suspend the timer.

Add info to the resource's description.

void Suspend(void)

Suspend the timer.

void Start(void)

Activate and start (or, restart after Suspend()) the timer.

void Start(void)

Activate and start (or, restart after Suspend()) the timer.

@ eStart

Call Start() immediately after creating.
