Interface AsyncEnumeratorResultCallback

public interface AsyncEnumeratorResultCallback

This interface is used for providing the Enumerator result of an asynchronous remote method call back to the method caller. This interface is used in two ways:

• an RPC client application may implement this interface and supply its instance to the RemoteReference.invoke(java.lang.String, java.lang.Class[], java.lang.Object[], com.prosyst.mprm.backend.rpc.AsyncEnumeratorResultCallback) or RemoteReference.sortedInvoke(java.lang.String, java.lang.Class[], java.lang.Object[], boolean, com.prosyst.mprm.backend.rpc.AsyncEnumeratorResultCallback) methods. This instance will be then called back by the RCP service to mutiple times to supply the application with all elements of the Enumerator result when they become available.
• an RCP-callable service (a server application) may declare its remote method(s) which produce mupltiple elements as result with AsyncEnumeratorResultCallback last argument, which means that the method is implemented asynchronously and application will return the Enumerator elements later through this argument.

Method Summary

Modifier and Type	Method and Description
void	error(RPCException exception) Invoked when the rpc method call results with an exception.
void	nextResultElement(java.lang.Object nextElement) Invoked when next element of the Enumerator result of the rpc method call becomes available.
void	resultFinished() Invoked to indicate that there are no more elements in the Enumerator result.

Method Detail

nextResultElement

void nextResultElement(java.lang.Object nextElement)

Invoked when next element of the Enumerator result of the rpc method call becomes available. This method is invoked mupltiple times (0 or more) for every single element of the Enumerator. nextElement the next elemenent of the Enumerator result.

resultFinished

void resultFinished()

Invoked to indicate that there are no more elements in the Enumerator result.

error

void error(RPCException exception)

Invoked when the rpc method call results with an exception.

Throws:

the - exception occured during the remote call.
