Interface VersionedBytesStore

All Superinterfaces:

KeyValueStore<Bytes,byte[]>, ReadOnlyKeyValueStore<Bytes,byte[]>, StateStore, TimestampedBytesStore

@Public
public interface VersionedBytesStore
extends KeyValueStore<Bytes,byte[]>, TimestampedBytesStore

A representation of a versioned key-value store as a KeyValueStore of type <Bytes, byte[]>. See VersionedBytesStoreSupplier for more.

Method Summary

Modifier and Type	Method	Description
byte[]	delete(Bytes key, long timestamp)	The analog of VersionedKeyValueStore.delete(Object, long).
byte[]	get(Bytes key, long asOfTimestamp)	The analog of VersionedKeyValueStore.get(Object, long).
long	put(Bytes key, byte[] value, long timestamp)	The analog of VersionedKeyValueStore.put(Object, Object, long).
default VersionedBytesStore	readOnly(IsolationLevel isolationLevel)	Return a read-only view of this store bound to the given IsolationLevel.

Method Details

put

long put(Bytes key,
 byte[] value,
 long timestamp)

The analog of VersionedKeyValueStore.put(Object, Object, long).

get

byte[] get(Bytes key,
 long asOfTimestamp)

The analog of VersionedKeyValueStore.get(Object, long).

delete

byte[] delete(Bytes key,
 long timestamp)

The analog of VersionedKeyValueStore.delete(Object, long).

readOnly

default VersionedBytesStore readOnly(IsolationLevel isolationLevel)

Return a read-only view of this store bound to the given IsolationLevel. Covariantly narrows ReadOnlyKeyValueStore.readOnly(IsolationLevel) so callers retain access to the versioned read methods (get(Bytes, long) and friends).

Specified by:

readOnly in interface ReadOnlyKeyValueStore<Bytes,byte[]>

Parameters:

isolationLevel - the isolation level the returned view should use for reads.

Returns:

a read-only view of this store using the given isolation level.
