Creating New Statistics Programmatically

//Get StatisticsFactory 
StatisticsFactory* factory = StatisticsFactory::getExistingInstance(); 
 
 
//Define each StatisticDescriptor and put each in an array 
StatisticDescriptor** statDescriptorArr = new StatisticDescriptor*[6]; 
statDescriptorArr[0] = statFactory->createIntCounter("IntCounter",
"Test Statistic Descriptor Int Counter.","TestUnit"); 
 
statDescriptorArr[1] = statFactory->createIntGauge("IntGauge",
"Test Statistic Descriptor Int Gauge.","TestUnit");
 
statDescriptorArr[2] = statFactory->createLongCounter("LongCounter",
"Test Statistic Descriptor Long Counter.","TestUnit");
 
statDescriptorArr[3] = statFactory->createLongGauge("LongGauge",
"Test Statistic Descriptor Long Gauge.","TestUnit");
 
statDescriptorArr[4] = statFactory->createDoubleCounter("DoubleCounter",
"Test Statistic Descriptor Double Counter.","TestUnit");
 
statDescriptorArr[5] = statFactory->createDoubleGauge("DoubleGauge",
"Test Statistic Descriptor Double Gauge.","TestUnit");
 
 
//Create a StatisticsType 
StatisticsType* statsType = statFactory->createType("TestStatsType", 
"Statistics for Unit Test.",statDescriptorArr, 6); 
 
//Create Statistics of a given type 
Statistics* testStat = 
factory->createStatistics(statsType,"TestStatistics"); 
 
 
//Statistics are created and registered. Set and increment individual values 
Int statIdIntCounter = statsType->nameToId("IntCounter"); 
testStat->setInt(statIdIntCounter, 10 );
testStat->incInt(statIdIntCounter, 1 );
int currentValue = testStat->getInt(statIdIntCounter);
