parameter in config file

[tobias amft]

Hi,

currently I am implementing an own analyzer in PeerfactSim. I know that the analyser class has to be declared in the xml config file of the experiment. e.g.:
<Analyzer class="org.peerfact.impl.overlay.dht.chord.chord.analyzer.myAnalyzer" />.

My question now is:
how can one hand over parameter to the class?

e.g.:
<Analyzer
    class="org.peerfact.impl.overlay.dht.chord.chord.analyzer.myAnalyzer"
    param1 = "..."
    param2 = "..."
/>

Is it possible to reach the variables directly if param1 and param2 are declared public in my analyzer class?
Or do I have to use getter/setter methods?
Or  do I have to change the Scenario Builder or something like that?

best regards
Tobi

Hey Tobias,

yes, setter-methods are the way to go. For each parameter you add in the config file, the engine searches for a setter-method within the class specified. In your example, you would have to add a method setParam1(<typeOfParameter>). param1 and param2 would be declared private in your class but are modified via the setter-methods anyway.

This works for the host builder and should also work for analyzers. Quite simple. :-)

Philipp
