Detailed Description

Function Documentation

invokeCountGet()

zfindex ZFCoreStatistic::invokeCountGet ( const zfstring & key )

extern

get ZFCoreStatistic::invokeCountLog's invoke count

for debug performance use only, used to log a method's invoke count, usage:

void yourFuncToTest(void) {
    ZFCoreStatistic::invokeCountLog(yourKeyOrNull);
}
void YourTestFunc(void) {
    // this is yourFuncToTest's invoke times
    zfindex yourFuncCalledTime = ZFCoreStatistic::invokeCountGet(yourKeyOrNull);
    // if you want to reset it:
    ZFCoreStatistic::invokeCountReset(yourKeyOrNull);
}

Note

this method is not thread-safe

invokeTimeLogBegin()

void ZFCoreStatistic::invokeTimeLogBegin ( const zfstring & key )

extern

util to log function's invoke time

usage:

ZFCoreStatistic::invokeTimeLogBegin(key);
yourHeavyFunc();
ZFCoreStatistic::invokeTimeLogEnd(key);
// ...
// you may call any times
 
// finally, print result, and remove
ZFLogTrim() << ZFCoreStatistic::invokeTimeGetSummary(key);
ZFCoreStatistic::invokeTimeRemove(key);
 
// or, you may use the convenient macro to log and output for one time
{
    ZFCoreStatisticInvokeTimeLoggerOneTime(key, optional_outputCallback);
    yourHeavyFunc();
}
