Ok, will look at that.

I understand the reason, but if you think you can prevent users from writing
ugly code or shooting themselves in the foot....think again, or see below :)
I wrote my own getRefCount. Now it is up to you to decide if we(the users)
should use this method or if you should add a public getRefCount method. ;)
void LogCallback(const char *pszText, int size, void *pData)
{
int rc;
const char *pTmp = pszText;
while(*pTmp == ' ')
pTmp++;
int r = sscanf(pTmp, "RefCount : %x", &rc);
if(r == 1)
{
*((int *)pData) = rc;
}
}
int getRefCount(OSG::FieldContainerPtr &fc)
{
int refCount = 0;
if(fc != NullFC)
{
LogBuf &lb = osgLog().getLogBuf();
lb.setCallback(LogCallback, &refCount, true);
LogType lt = osgLog().getLogType();
osgLog().setLogType(OSG::LOG_BUFFER);
fc.dump(0, OSG::FCDumpFlags::RefCount);
lb.removeCallback();
osgLog().setLogType(lt);
}
return refCount;
}
