Methods

Modifier and Type	Method and Description
long	getLastLocalNodeId() The last allocated local and replicated node ids are used for ckpts.
long	getLastReplicatedNodeId()
long	getNextLocalNodeId() We get a new node id of the appropriate kind when creating a new node.
long	getNextReplicatedNodeId()
long	getNextTransientNodeId()
(package private) void	initRealNodeId() Initialize the counters in these methods rather than a constructor so we can control the initialization more precisely.
(package private) void	initTransientNodeId() Initialize the counters in these methods rather than a constructor so we can control the initialization more precisely.
void	setLastNodeId(long lastReplicatedNodeId, long lastLocalNodeId) Initialize the node ids, from recovery.

Method Detail

initTransientNodeId

void initTransientNodeId()

Initialize the counters in these methods rather than a constructor so we can control the initialization more precisely.

initRealNodeId

void initRealNodeId()

Initialize the counters in these methods rather than a constructor so we can control the initialization more precisely.

getLastLocalNodeId

public long getLastLocalNodeId()

The last allocated local and replicated node ids are used for ckpts.

getLastReplicatedNodeId

public long getLastReplicatedNodeId()

getNextLocalNodeId

public long getNextLocalNodeId()

We get a new node id of the appropriate kind when creating a new node.

getNextReplicatedNodeId

public long getNextReplicatedNodeId()

getNextTransientNodeId

public long getNextTransientNodeId()

setLastNodeId

public void setLastNodeId(long lastReplicatedNodeId,
                 long lastLocalNodeId)

Initialize the node ids, from recovery. No need to initialize the transient node ids, since those can be reused each time the environment is recreated.

updateFromReplay

public void updateFromReplay(long replayNodeId)
