Method Detail

cancel

public void cancel()

Specified by:

cancel in interface NodeReindexService

start

public void start()

Specified by:

start in interface NodeReindexService

pause

public void pause()

Description copied from interface: NodeReindexService

Pause the service. This will wait for any current execution of the service polling to finish.

Specified by:

pause in interface NodeReindexService

restart

public void restart()

Specified by:

restart in interface NodeReindexService

resetIndexCount

public void resetIndexCount()

Description copied from interface: NodeReindexService

Reset the index count to the last entry in the NodeIndexOperation table for each node. This is done to mark the current state before getting a new index copy or performing a full reindex.

It would normally be done immediately following a pause() of the service.

Specified by:

resetIndexCount in interface NodeReindexService

canIndexBeRebuilt

public boolean canIndexBeRebuilt()

Description copied from interface: NodeReindexService

Returns true if the index on the invoking node can be rebuilt from the information contained in the ReplicatedIndexOperationStore. If the ReplicatedIndexOperationStore is empty then it is assumed the index can be rebuilt.

Specified by:

canIndexBeRebuilt in interface NodeReindexService

Returns:

true if the index can be rebuilt

replayLocalOperations

public void replayLocalOperations()

Description copied from interface: NodeReindexService

This will replay any local operations that may have been lost when a index is copied from another node in the cluster

Specified by:

replayLocalOperations in interface NodeReindexService
