Examples of de.danet.an.workflow.api.MethodInvocationBatch

de.danet.an.workflow.api.MethodInvocationBatch
This class provides a {@link Batch Batch}implementation that executes several invocations of remote objects on the server in a single transaction and returns the results. This class can be thought of as a "generic DTO". @author @version $Revision: 2893 $
