◆ adoptAndReplaceCachedMessage()

DataAllocator::CacheId o2::framework::CCDBHelpers::adoptAndReplaceCachedMessage ( DataAllocator &  allocator,
std::unordered_map< std::string, DataAllocator::CacheId > const &  cache,
std::string const &  path,
Output const &  output,
o2::pmr::vector< char > &&  v,
o2::header::SerializationMethod  method 
)
static

Adopt a freshly-fetched CCDB payload as a new SHM message and prune the previously cached one for this path. The new SHM message is adopted BEFORE the old cached one is pruned allocator producer-device DPL DataAllocator cache read-only view of the producer-local path -> CacheId map; path CCDB path output DPL Output matcher v freshly-fetched CCDB payload; consumed by the call, leaving v empty method serialization-method tag written into the message header

Returns
the new CacheId; the caller must record it in its map
