Update()

lldb::ChildCacheState VectorIteratorSyntheticFrontEnd::Update ( )

overridevirtual

This function is assumed to always succeed and if it fails, the front-end should know to deal with it in the correct way (most probably, by refusing to return any children).

The return value of Update should actually be interpreted as "ValueObjectSyntheticFilter cache is good/bad". If this function returns lldb::ChildCacheState::eReuse, ValueObjectSyntheticFilter is allowed to use the children it fetched previously and cached. Otherwise, ValueObjectSyntheticFilter must throw away its cache, and query again for children.
