示例1: getInstance
//
// public static methods
//
Tracer* Tracer::getInstance(const char* tracername, const char* classname)
{
QString strTracername(tracername);
QString strClassname(classname);
// if neither tracername nor classname is specified we return the root-tracer
if (strTracername.isEmpty() && strClassname.isEmpty()) {
return getRootTracer();
}
Tracer* currentTracer = getRootTracer();
QString currentTracerName = QString("");
// split the tracername into its parts
QStringList parts = QStringList::split(TRACER_NAME_SEPARATOR, strTracername, false);
// if specified the classname is handled as last part of the tracername
if (!strClassname.isEmpty()) {
parts.append(strClassname);
}
int partsCount = parts.count();
// loop over the tracename parts and
// try to get the tracer matching the tracername and classname
// as soon as we don't find a matching subtracer we begin to create new tracers...
for (int i = 0; i < partsCount; i++) {
QString part = parts[i];
// create the tracername of the tracer we would like at this point
if (i > 0) {
currentTracerName = currentTracerName.append(TRACER_NAME_SEPARATOR);
}
currentTracerName = currentTracerName.append(part);
// try to get a matching tracer for the currentTracerName
Tracer* matchingChild = currentTracer->getChild(part);
if (matchingChild) {
currentTracer = matchingChild;

//no matching subtracer found --> create one!

if (i + 1 == partsCount) {
// this is the last tracer to instantiate --> create WITH classname
child = new Tracer(currentTracerName, part, strClassname);
} else {
// this is a missing supertracer of the tracer to create --> create without classname
child = new Tracer(currentTracerName, part, "");

// --> force the classname
