                    throws Exception

Overrides:

innerBeforeRun in class KeyBasedMapOperation

Throws:

Exception

run

public void run()

Specified by:

run in class Operation

shouldWait

public boolean shouldWait()

Specified by:

shouldWait in interface WaitSupport

Overrides:

shouldWait in class LockAwareOperation

afterRun

public void afterRun()

Overrides:

afterRun in class BaseRemoveOperation

onWaitExpire

public void onWaitExpire()

Specified by:

onWaitExpire in interface WaitSupport

Overrides:

onWaitExpire in class BaseRemoveOperation

getVersion

public long getVersion()

Specified by:

getVersion in interface MapTxnOperation

setVersion

public void setVersion(long version)

Specified by:

setVersion in interface MapTxnOperation

getResponse
