Method Detail

run

public void run()

Specified by:

run in class Operation

afterRun

public void afterRun()

Overrides:

afterRun in class BasePutOperation

getResponse

public Object getResponse()

Overrides:

getResponse in class Operation

shouldBackup

public boolean shouldBackup()

Description copied from interface: BackupAwareOperation

Checks if a backup needs to be made.

If a call has not made any change, e.g. an AtomicLong increment with 0, no backup needs to be made.
