Examples of org.rioproject.opstring.OperationalString

org.rioproject.opstring.OperationalString
An OperationalString represents a collection of application and/or infrastructure software services that when put together provide a coarse-grained service, typically distributed through the network.
The {@code OperationalString} is the unit of deployment in Rio, andprovides the capability to declare, monitor and manage the availability of enclosed services. @author Dennis Reedy
