public abstract class StatCollectorCond
- extends StatCollector
- implements Conditional
Collects and stores aggregate statistics on some data source for every specified measurement type
of that source, and for each succesive measurement of that source, while that source meets some condition.
See StatCollector documentation for a discussion of how to use stat collectors.
Conditional stat collectors allow you to specifiy a condition that must be met for a statistic to be measured for
an object. In Ascape, they are useful in cases where you want to collect statistics automatically, but you want to
restrict the statistic to some subpopulation of a scape.
The following example creates an anonymous class that gathers age statistics for agents with wealth over 50,000, and adds
it to the parent scape so it can be collected.
scape.addStatCollector(new StatCollectorCSA("Age") {
public boolean meetsCondition(Object object) {
return ((AnObjectWithWealth) object).getWealth() >= 50000;
}
public double getValue(Object object) {
return ((AnObjectWithAge) object).getAge();
}
}
