public enum JobClassType
extends Enum<JobClassType>

Enumeration of job class types in queueing network models.

Job classes represent different categories of customers or workloads in a queueing network. Each class can have distinct service requirements, routing behavior, and performance characteristics. The type of a job class determines its fundamental behavior in the network.

The three types are:

• OPEN: Jobs arrive from external sources and eventually leave the system
• CLOSED: Fixed population of jobs that circulate indefinitely in the network
• DISABLED: Job class is inactive and not processed by the network

Networks can contain a mix of open and closed classes, forming a mixed queueing network. Open classes model external arrivals (e.g., web requests), while closed classes model finite resources (e.g., thread pools).
