Class ExperimentImpl
is a simple implementation of
Experiment
which repeat the execution of a single
scenario a certain number of times and returns a single
Stats object containing a summary of the statistics for all the
executions.
Field Summary | |
protected boolean |
clear
If true, the scenario will be cleared between iterations of the experiment |
protected boolean |
debug
If true, methods for the analysis of experiment footprint are invoked |
protected Factory |
factory
Factory used to instantiate objects |
protected int |
iterations
Number of times a scenario is evaluated |
static java.lang.String |
ROUND_NUMBER
The identifier of the counter used in a Stats object to
count the number of repetitions of the scenario evaluation in a
experiment. |
protected Scenario |
scenario
Scenario on which evaluate the experiment |
protected int |
scenarioVersion
Version identifier of the scenario; when init params change, the version increase |
Constructor Summary | |
ExperimentImpl(Factory factory,
int iterations)
Instantiates a new experiment by setting the given number of times by which a scenario has to be evaluated. |
