Hi everyone!
I'm trying to use the type-safe enumeration in my project (COCOMO II
implementation). I won't give too much details, but the COCOMO model
consists of a serie of parameteres rated from Very-low to Very-high and the
model make some calculations with these parameters.
So, I wrote a Class to hold my parameters (enumerations):
public class Parameters {
public enum PREC implements FatorEscala {
VERY_LOW(6.20f), LOW(4.96f), NOMINAL(3.72f), HIGH(2.48f),
VERY_HIGH(1.24f), EXTRA_HIGH(0);
private final float valor;
PREC(float value) {
this.valor = value;
}
public float valor() {
return valor;
}
}
public enum FLEX {
VERY_LOW(5.07f), LOW(4.05f), NOMINAL(3.04f), HIGH(2.03f),
VERY_HIGH(1.01f), EXTRA_HIGH(0);
private final float valor;
FLEX(float value) {
this.valor = value;
}
public float valor() {
return valor;
}
}
// A bunch of other parameters defined in same way above.....
}
Now I want to have a variable in another class which is a collection of
theese paramenters (enumerations) rather defining one variable for each
enumeration.
I supose I have to make these enumerations to implement same interface to
acomplish that, right? I'd like to write something like:
List<IParameter> parameters = new ArrayList<IParameter>();
parameters.add(Parameters.PREC.LOW);
parameters.add(Parameters.FLEX.HIGH);
This way I can iterate over the collection and get the sum or the product of
the parameters values.
How can I acomplish this??
Thanks for any help.
Vitor.
