Transferring data from the server to the client

Transport additional data from server to client – NuclosRemoteInvocationResult and userObject.

Auf dieser Seite

To transport additional data (besides the actual result) from the server to the client, there are NuclosRemoteInvocationResult and NuclosHttpInvokerServiceExporter.

Mechanism

NuclosRemoteInvocationResult contains the usual server result plus an optional userObject.
The server sets the object in NuclosHttpInvokerServiceExporter.invokeAndCreateResult.
The client reads it in NuclosHttpInvokerProxyFactoryBean.executeRequest after the server call and processes it.

final RemoteInvocationResult result = super.executeRequest(invocation);
if(result instanceof NuclosRemoteInvocationResult) {
	NuclosRemoteInvocationResult nuclosResult = (NuclosRemoteInvocationResult) result;
    // space for future use of this feature
}

Originally intended for statistics (e.g. number of SQL calls or duration of a server call) – better than digging through log files.
