Member Data Documentation

matcherToEntry

std::unordered_map<std::string, Entry> o2::framework::ObjectCache::matcherToEntry

A per-path cache for deserialised objects. This keeps a mapping so that we can tell if a given path was already received and it's blob stored in .second.obj

Definition at line 60 of file ObjectCache.h.

matcherToMetadata

std::unordered_map<std::string, MetadataEntry> o2::framework::ObjectCache::matcherToMetadata

A per-path cache to the deserialised metadata We keep it separate because we want to avoid that looking up the metadata also pollutes the object cache.
