Type Members

trait Component extends Identifiable with Locatable
The Component trait provides basic common feature for simulation components.
The Component trait provides basic common feature for simulation components. The list of subparts is empty for atomic components and nonempty for composite components.
abstract class Coroutine extends Runnable with Error
The Coroutine class supports (one-at-a-time) quasi-concurrent programming.
The Coroutine class supports (one-at-a-time) quasi-concurrent programming. A coroutine runs/acts until it yields control from 'this' to 'that' coroutine. When resumed, a coroutines continues its execution where it left off.
class Gate extends SimActor with Component
The Gate class models the operation of gate that can open and shut.
The Gate class models the operation of gate that can open and shut. When the gate is open, entities can flow through and when shut, they cannot. They may wait in a queue or go elsewhere. A gate can model a traffic light (green => open, red => shut).
class Junction extends Component
The Junction class provides a connector between two Transports/Routes.
The Junction class provides a connector between two Transports/Routes. Since Lines and QCurves have limitations (e.g., hard to make a loop back), a junction may be needed.
class Model extends Coroutine with Modelable with Component
The Model class maintains a list of components making up the model and controls the flow of entities (SimActors) through the model, following the process-interaction world-view.
The Model class maintains a list of components making up the model and controls the flow of entities (SimActors) through the model, following the process-interaction world-view. It maintains a time-ordered priority queue to activate/re-activate each of the entities. Each entity (SimActor) is implemented as a Scala Actor and may be thought of as running in its own thread.
class Resource extends Component
The Resource class provides services to entities (SimActors).
The Resource class provides services to entities (SimActors). It may or may not have an associated waiting queue.
class Route extends Component
The Route class provides a multi-lane pathway between two other components.
The Route class provides a multi-lane pathway between two other components. The components in a Model conceptually form a graph in which the edges are Transports and the nodes are other Components. A Route is a composite component that bundles several Transports.
abstract class SimActor extends Coroutine with PQItem with Ordered[SimActor] with Locatable with Error
The SimActor abstract class represents entities that are active in the model.
The SimActor abstract class represents entities that are active in the model. The 'act' abstract method, which specifies entity behavior, must be defined for each subclass. Each SimActor extends Scala's Actor class and may be roughly thought of as running in its own thread.
class Sink extends Component
The Sink class is used to terminate entities SimActors when they are finished.
class Source extends SimActor with Component
The Source class is used to periodically inject entities (SimActors) into a running simulation model.
The Source class is used to periodically inject entities (SimActors) into a running simulation model. May act as an arrival generator. Source is both a simulation Component and special SimActor and therefore runs in own thread.
class Transport extends Component
The Transport class provides a pathway between two other components.
The Transport class provides a pathway between two other components. The components in a Model conceptually form a 'graph' in which the 'edges' are Transports and the 'nodes' are other Components.
class WaitQueue extends Queue[SimActor] with Component
The WaitQueue class is a wrapper for Scala's Queue class, which supports First-Come, First-Serve 'FCSC' Queues.
The WaitQueue class is a wrapper for Scala's Queue class, which supports First-Come, First-Serve 'FCSC' Queues. It adds monitoring capabilities and optional capacity restrictions. If the queue is full, entities (SimActors) attempting to enter the queue are 'barred'. At the model level, such entities may be (1) held in place, (2) take an alternate route, or (3) be lost (e.g., dropped call/packet).

Value Members

object Coroutine extends Error
The Coroutine companion object provides functions to start-up and shutdown the coroutine system as well as counters for the Coroutine class.
object CoroutineTest extends App
The CoroutineTest object is used to test the Coroutine class.
The CoroutineTest object is used to test the Coroutine class. Should print: Cor1: phase 1 Cor2: phase 1 Cor1: phase 2 Cor2: phase 2
object Gate
The Gate companion object provides a builder method for gates.
object Junction
The Junction companion object provides a builder method for sinks.
object Model
The Model companion object provides a shutdown method.
object ModelTest extends App
The ModelTest object is used to test the Model class.
The ModelTest object is used to test the Model class. Caveat: must add 'from' and 'to' components before transport!!
object Resource
The Resource companion object provides a builder method for resources.
object RouteTest extends App
The RouteTest object is used to test the Route class, which is a composite class.
The RouteTest object is used to test the Route class, which is a composite class. It simulates a two-lane road in one direction.
object Sink
The Sink companion object provides a builder method for sinks.
object Source
The Source companion object provides a builder method for sources.
object WaitQueue extends Serializable
The WaitQueue companion object provides a builder method for wait-queues.
