void |
beforeRun()
The beforeRun is called before either the
Operation.run() or the Operation.call() method is called. |
int |
getClassId()
Returns type identifier for this class.
|
int |
getFactoryId()
Returns DataSerializableFactory factory ID for this class.
|
Object |
getResponse()
Called if and only if
Operation.returnsResponse() returned true ,
shortly after Operation.run() returns. |
String |
getServiceName() |

returnsResponse()
Method is intended to be overridden.
|
void |
run()
Runs the operation.

Operation.run()

method is called.

Operation.call()
public boolean returnsResponse()
Operation
true
,
Operation.getResponse()
will be called right after Operation.run()
method.
If it returns false
, Operation.sendResponse(Object)
must be
called later to finish the operation.
In other words, true
is for synchronous operation and
false
is for asynchronous one.
Default implementation is synchronous operation (true
).
