Constructor Detail

DevStoneGenerator

public DevStoneGenerator(String name,
                         double preparationTime,
                         double period,
                         int maxEvents)

Constructor

Parameters:

name - name of the model

preparationTime - preparation time

period - period

maxEvents - maximum number of events to generate

DevStoneGenerator

public DevStoneGenerator(Element xmlAtomic)

Constructor

Parameters:

xmlAtomic - XML element with the description of the atomic model

Method Detail

initialize

public void initialize()

Description copied from class: Component

Initialize the component. The initialize method is called when the simulation starts. The initialize method is used to initialize the component before the simulation starts.

Specified by:

initialize in class Component

exit

public void exit()

Description copied from class: Component

Exit function. The exit function is called when the simulation ends. The exit function is used to release resources used by the component.

Specified by:

exit in class Component

deltint

public void deltint()

Description copied from class: Atomic

Internal transition method of the atomic model. This method is called when the time until the next internal transition of the model is zero.

Specified by:

deltint in class Atomic

deltext

public void deltext(double e)

Description copied from class: Atomic

External transition method of the atomic model. This method is called when the model receives an input from another model.

Specified by:

deltext in class Atomic

Parameters:

e - The time elapsed since the last internal transition of the model.

lambda

public void lambda()

Description copied from class: Atomic

Output function of the atomic model. This method is called when the model has an output to send to another model.

Specified by:

lambda in class Atomic

getPeriod

public double getPeriod()

Get the period

Returns:

period

getMaxEvents

public int getMaxEvents()

Get the maximum number of events to generate

Returns:

maximum number of events

getPreparationTime

public double getPreparationTime()

Get the preparation time

Returns:

preparation time

toXml

public String toXml()

Description copied from class: Atomic

Method to get the XML representation of the model.

Overrides:

toXml in class Atomic

Returns:

The XML representation of the model.
