public enum NodeType extends Enum<NodeType>
Enumeration of node types available in queueing network models.

Each node type represents a different functional component in a queueing network, with specific behavior for processing, routing, or transforming jobs. Nodes are the fundamental building blocks that are connected to form complete network models.

Node categories include:

  • Service nodes: Queue, Delay - process jobs with service times
  • Routing nodes: Router, Fork, Join - control job flow
  • Source/Sink nodes: Source, Sink - job creation and destruction
  • Special nodes: Cache, ClassSwitch, Logger - specialized functionality
  • Petri net nodes: Place, Transition - for Petri net models

Since:
1.0
