Local handle is referenced by data structure: handle stack
when 'scope' disposed, related local handles in handle stack will be
release.
More details:
HandleScope::~HandleScope() {
if (!is_closed_) {
Leave();
}
}
void HandleScope::Leave() {
// ......
i::HandleScope::DeleteExtensions(isolate_);
// ......
}
}
Method DeleteExtensions() is implemented in Api.h,
named HandleScopeImplementer::DeleteExtensions()
