Constructor Detail

ReplicatedMapEntryStages

public ReplicatedMapEntryStages()

Method Detail

timestamp

public long timestamp()

entryDeleted

public boolean entryDeleted()

Overrides:

entryDeleted in class MapEntryStages<K,V>

writeEntryPresent

public void writeEntryPresent()

writeEntryDeleted

public void writeEntryDeleted()

originIdentifier

public byte originIdentifier()

Description copied from interface: net.openhft.chronicle.hash.replication.ReplicableEntry

The identifier, associated with this entry. Originally, and by default, this identifier means the identifier of the ChronicleHash node on which this entry was updated last.

When the entry is replicated, this identifier comes to remote nodes as RemoteOperationContext.remoteIdentifier().

On ChronicleHash local operations with entries, like Map.put( Object, Object), this identifier is overwritten to the own ChronicleHash Replica.identifier(). On remote operations, proxied through MapRemoteOperations or SetRemoteOperations, you are free to overwrite this identifier to any value, using ReplicableEntry.updateOrigin(byte, long) method.

Specified by:

originIdentifier in interface net.openhft.chronicle.hash.replication.ReplicableEntry

Returns:

the identifier, associated with this entry

originTimestamp

public long originTimestamp()

Description copied from interface: net.openhft.chronicle.hash.replication.ReplicableEntry

The timestamp of the last update to this entry.

When the entry is replicated, this timestamp comes to remote nodes as RemoteOperationContext.remoteTimestamp().

Specified by:

originTimestamp in interface net.openhft.chronicle.hash.replication.ReplicableEntry

Returns:

the timestamp of the last update to this entry

TimeProvider

updateOrigin

public void updateOrigin(byte newIdentifier,
                         long newTimestamp)

Description copied from interface: net.openhft.chronicle.hash.replication.ReplicableEntry

Overwrite the entry's associated identifier and timestamp. After this call ReplicableEntry.originIdentifier() returns the given newIdentifier and ReplicableEntry.originTimestamp() returns the given newTimestamp respectively.

Specified by:

updateOrigin in interface net.openhft.chronicle.hash.replication.ReplicableEntry

Parameters:

newIdentifier - the new identifier for the entry

newTimestamp - the new timestamp for the entry

dropChanged

public void dropChanged()

Description copied from interface: net.openhft.chronicle.hash.replication.ReplicableEntry

Suppress the entry, if it was scheduled to be replicated over to all remote Chronicle nodes.

Specified by:

dropChanged in interface net.openhft.chronicle.hash.replication.ReplicableEntry

dropChangedFor

public void dropChangedFor(byte remoteIdentifier)

Description copied from interface: net.openhft.chronicle.hash.replication.ReplicableEntry

Suppress the entry, if it was scheduled to be replicated over to the remote Chronicle node with the specified identifier.

Specified by:

dropChangedFor in interface net.openhft.chronicle.hash.replication.ReplicableEntry

raiseChanged

public void raiseChanged()

Description copied from interface: net.openhft.chronicle.hash.replication.ReplicableEntry

Propagate the entry, schedule it to be replicated over to all remote Chronicle nodes.

Specified by:

raiseChanged in interface net.openhft.chronicle.hash.replication.ReplicableEntry

raiseChangedFor

public void raiseChangedFor(byte remoteIdentifier)

Description copied from interface: net.openhft.chronicle.hash.replication.ReplicableEntry

Propagate the entry, schedule it to be replicated over to the remote Chronicle node with the specified identifier.

Specified by:

raiseChangedFor in interface net.openhft.chronicle.hash.replication.ReplicableEntry

Parameters:

remoteIdentifier - the identifier of the node to replicate this entry to

raiseChangedForAllExcept

public void raiseChangedForAllExcept(byte remoteIdentifier)

Description copied from interface: net.openhft.chronicle.hash.replication.ReplicableEntry

Propagate the entry, schedule it to be replicated over to all remote Chronicle nodes, except the node with the specified identifier.

Specified by:

raiseChangedForAllExcept in interface net.openhft.chronicle.hash.replication.ReplicableEntry

Parameters:

remoteIdentifier - the identifier of the node not to replicate this entry to

isChanged

public boolean isChanged()

Description copied from interface: net.openhft.chronicle.hash.replication.ReplicableEntry

Check is the entry is scheduled to be replicated to the remote Chronicle nodes, to which the connection is currently established.

Specified by:

isChanged in interface net.openhft.chronicle.hash.replication.ReplicableEntry

Returns:

true is the entry is "dirty" locally, i. e. should be replicated to any of remote Chronicle nodes, false otherwise

updatedReplicationStateOnPresentEntry

public void updatedReplicationStateOnPresentEntry()

updatedReplicationStateOnAbsentEntry

public void updatedReplicationStateOnAbsentEntry()

relocation

protected void relocation(Data<V> newValue,
                          long newEntrySize)
