示例1: vpath
bool
commit::isCommitPathEffective(Cstore& cs, const Cpath& pcomps,
tr1::shared_ptr<Ctemplate> def,
bool in_active, bool in_working)
{
if (in_active && in_working) {
// remain the same
return true;
}
if (!in_active && !in_working) {
// doesn't exist
return false;
}
// at this point, in_active corresponds to "being deleted"
if (def->isTagNode()) {
// special handling for tag nodes, which are never marked
vector<string> tvals;
// get tag values from active or working config
cs.cfgPathGetChildNodes(pcomps, tvals, in_active);
Cpath vpath(pcomps);
/* note that there should be at least 1 tag value since tag node
* cannot exist without tag value.
*/
for (size_t i = 0; i < tvals.size(); i++) {
vpath.push(tvals[i]);
if (in_active) {
// being deleted => all tag values are being deleted
if (!cs.cfgPathMarkedCommitted(vpath, true)) {

* => a tag value has not been deleted
