All Implemented Interfaces:

Clearable, Scenario

public class ScenarioImpl

extends Object

implements Scenario

Class ScenarioImpl is a simple implementation of interface Scenario in which a predefined set of resources is inserted in the network and then a certain number of requests are performed and simulate. Initial resources are generated and distributed in the network using a ResourceGenerator object; at runtime, requests are generated using a RequestGenerator object.

Constructor Detail

ScenarioImpl

public ScenarioImpl(Factory factory,
                    String name)

Instantiates a new ScenarioImpl.

Parameters:

factory - the factory to be used to read configuration arguments and to create other configurable objects

name - the name that is associated to this instance in the configuration file

Method Detail

clear

public void clear()

Restores the object to its initial state.

Specified by:

clear in interface Clearable

setStats

public void setStats(Stats stats)

Set the statistics object which will be used throughout the scenario evaluation.

Specified by:

setStats in interface Scenario

Parameters:

stats - the object used to collect statistics

evaluate

public void evaluate()

Perform the evaluation of this scenario object by simulating it. The simulation is subdivided in rounds. At each iteration, a new request is generated and assigned to one of the nest included in the simulated peer network, which generates an ant for it. Furthermore, for each nest, an ant included in the manager queue is selected and its run() method is executed. Statistics about the simulated execution of the code are collected in the Stats object specified through method setStats().

Specified by:

evaluate in interface Scenario

analyze

public void analyze(Stats stats)

Analyze the scenario object by displaying information about it. The behavior of this method is delagated to an instance of ScenarioAnalyzer.

Specified by:

analyze in interface Scenario
