Method Detail

run

public void run()

Description copied from class: Operation

Runs the operation. Either the Operation.run() or Operation.call() method should be implemented; not both. Runs after wait-support, supposed to do actual operation

Overrides:

run in class Operation

See Also:

Operation.call()

returnsResponse

public boolean returnsResponse()

Description copied from class: Operation

Method is intended to be overridden. If it returns 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).

Overrides:

returnsResponse in class Operation

getResponse

public Object getResponse()

Description copied from class: Operation

Called if and only if Operation.returnsResponse() returned true, shortly after Operation.run() returns.

Overrides:

getResponse in class Operation

getServiceName

public String getServiceName()

Overrides:

getServiceName in class Operation

onInvocationException

public ExceptionAction onInvocationException(Throwable throwable)

Description copied from class: Operation

Called when an Exception/Error is thrown during an invocation. Invocation process will continue, it will retry or fail according to returned ExceptionAction.

This method is called on caller side of the invocation.

Overrides:

onInvocationException in class Operation

Parameters:

throwable - Exception/Error thrown during invocation

Returns:

ExceptionAction

readInternal

protected void readInternal(ObjectDataInput in)
                     throws IOException

Overrides:

readInternal in class Operation

Throws:

IOException

writeInternal

protected void writeInternal(ObjectDataOutput out)
                      throws IOException

Overrides:

writeInternal in class Operation

Throws:

IOException

getId

public int getId()

Description copied from interface: IdentifiedDataSerializable

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

Specified by:

getId in interface IdentifiedDataSerializable

Returns:

type ID

getFactoryId

public final int getFactoryId()

Description copied from interface: IdentifiedDataSerializable

Returns DataSerializableFactory factory ID for this class.

Specified by:

getFactoryId in interface IdentifiedDataSerializable

Returns:

factory ID
