Method Detail

run

public void run()
         throws Exception

Specified by:

run in class Operation

Throws:

Exception

shouldWait

public boolean shouldWait()

Specified by:

shouldWait in interface BlockingOperation

Overrides:

shouldWait in class LockAwareOperation

onWaitExpire

public void onWaitExpire()

Specified by:

onWaitExpire in interface BlockingOperation

Specified by:

onWaitExpire in class LockAwareOperation

getResponse

public Object getResponse()

Overrides:

writeInternal

protected void writeInternal(ObjectDataOutput out)
                      throws IOException

Overrides:

writeInternal in class MutatingKeyBasedMapOperation

Throws:

IOException

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException

Overrides:

readInternal in class MutatingKeyBasedMapOperation

Throws:

IOException

toString

protected void toString(StringBuilder sb)

Description copied from class: Operation

A template method allows for additional information to be passed into the Operation.toString() method. So an Operation subclass can override this method and add additional debugging content. The default implementation does nothing so one is not forced to provide an empty implementation. It is a good practice always to call the super.toString(stringBuffer) when implementing this method to make sure that the super class can inject content if needed.

Overrides:

toString in class AbstractNamedOperation

Parameters:

sb - the StringBuilder to add the debug info to.

getId

public int getId()

Description copied from interface: IdentifiedDataSerializable

Returns type identifier for this class. Id should be unique per DataSerializableFactory.

Specified by:

getId in interface IdentifiedDataSerializable

Returns:

type id
