public class SimpleAtomic
extends AtomicDevs

This class is a simple example of what can be a basic atomic model. This model changes its state, which is an integer, for every Message Content it receives (that is to say at each external or confluent transition). After an external or a confluent transition, the model waits for 10 units of time, while after an internal transition it goes in a passive state for an infinite amount of time.

Each transition is recorded for later displaying and analysis.

Field Detail

state

public int state

The state of the model. Changes at every external event.

eventsSet

public TreeMap<Double,LinkedList<String>> eventsSet

Used for storing the state of the model at each event.

Constructor Detail

SimpleAtomic

protected SimpleAtomic(String name)

Constructor that initializes the name of the model and its attributes (empty Tree and state to 0).

Parameters:

name - Name to give to the new instance.

Method Detail

storeEvent

public void storeEvent(Double time,
                       String method)

Store a new event in the event map.

Parameters:

time - The event occurrence date.

method - The event that happens.

initialize

public void initialize()

Initialize the model.

deltint

public void deltint()

The internal transition function.

deltext

public void deltext(Double timeElapsed,
                    Message x)

The external transition function.

Parameters:

timeElapsed - This time corresponds to the time to wait before the transition happens.

x - This is the message to be sent at the transition.

deltcon

public void deltcon(Double e,
                    Message x)

The confluent transition function that is called when both internal and external transitions should happen at the exactly same time.

Parameters:

e - This time corresponds to the time to wait before the transition happens.

x - This is the message to be sent at the transition.

lambda

public Message lambda()

Devs lambda function that makes the state becoming the model's output.

Returns:

an output message.

toString

public String toString()

Generate a string that represents the model state.

Overrides:

toString in class AtomicDevs

Returns:

A string that represents the model state.
