public record ObjectInfo(String pid, String cid, long size, Map<String,String> hexDigests) extends Record
This is the Metacat version of the ObjectMetadata of Hashstore ObjectMetadata is a class that models a unique identifier for an object in the HashStore. It encapsulates information about a file's authority-based/persistent identifier (pid), content identifier (cid), size, and associated hash digest values. By using ObjectMetadata objects, client code can easily obtain metadata of a store object in HashStore without needing to know the underlying file system details.
