Class ResolverMappingDigest

java.lang.Object

com.apple.foundationdb.record.provider.foundationdb.keyspace.ResolverMappingDigest

All Implemented Interfaces:

AutoCloseable

@API(EXPERIMENTAL)
public class ResolverMappingDigest
extends Object
implements AutoCloseable

Computes a message digest for all of the string to integer mappings in the provided LocatableResolver. This gives a way to easily verify that a copy operation performed by ResolverMappingReplicator succeeded. The digest is computed based on the Tuple serialization of the string and integer rather than the serialization used by LocatableResolver as that can vary depending on implementation.
