Well, without the benefit of SimGear as a whole, I've crafted a [probably
non-optimal]
property tree cataloging function for use in JSBSim. Thought you might like to
see it:
//%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
struct PropertyCatalogStructure {
string base_string;
FGPropertyManager *node;
};
void FGFDMExec::BuildPropertyCatalog(struct PropertyCatalogStructure* pcs)
{
struct PropertyCatalogStructure* pcsNew = new struct PropertyCatalogStructure;
int node_idx = 0;
char int_buf[10];
for (int i=0; i<pcs->node->nChildren(); i++) {
pcsNew->base_string = pcs->base_string + "/" +
pcs->node->getChild(i)->getName();
node_idx = pcs->node->getChild(i)->getIndex();
sprintf(int_buf, "[%d]", node_idx);
if (node_idx != 0) pcsNew->base_string += string(int_buf);
if (pcs->node->getChild(i)->nChildren() == 0) {
PropertyCatalog.push_back(pcsNew->base_string +
pcs->node->getChild(i)->getName());
} else {
pcsNew->node = (FGPropertyManager*)pcs->node->getChild(i);
BuildPropertyCatalog(pcsNew);
}
}
delete pcsNew;
}
//%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
It's called like this:
//%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
struct PropertyCatalogStructure masterPCS;
masterPCS.base_string = "";
masterPCS.node = (FGPropertyManager*)master;
BuildPropertyCatalog(&masterPCS);
cout << endl << "Registered properties: " << endl;
for (int i=0; i<PropertyCatalog.size(); i++) cout << PropertyCatalog[i] <<
endl;
//%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
