Examples of SequentialProcess

org.hive2hive.core.processes.framework.concretes.SequentialProcess
A process component container that executes and rollbacks its process components in a sequential manner. In presence of asynchronous child components, this container waits for all asynchronous operations to complete before continuing. @author Christian
