Enum NodeType
-
- All Implemented Interfaces:
public 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

Enum Constant Summary
Enum Constants Enum Constant Description Transition
Transition node in Petri net models - fires when enabled
Place
Place node in Petri net models - holds tokens
Fork
Fork node - splits jobs into parallel tasks
Router
Router node - directs jobs without service time
Cache
Cache node - implements cache replacement with hit/miss routing
Logger
Logger node - records job passage for monitoring
ClassSwitch
Class switch node - changes job class based on probabilities
Delay
Delay station - infinite servers with no queueing
Source
Source node - generates jobs according to arrival process
Sink
Sink node - removes completed jobs from the network
Join
Join node - synchronizes parallel tasks from fork
Queue
Queue station - finite servers with queueing

Method Detail

values
static Array<NodeType> values()
Returns an array containing the constants of this enum type, in the order they're declared. This method may be used to iterate over the constants.
- Returns:
an array containing the constants of this enum type, in the order they're declared
-
valueOf
static NodeType valueOf(String name)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
- Returns:
the enum constant with the specified name
