An EnumeratedObject represents a guaranteed object that is explicitly defined and given a name in the model file, using a statement like:
guaranteed typename name1, name2, ..., nameN
A "name" is really a nonrandom constant symbol that refers to this object. Other constant symbols may also refer to this object, but in presenting query results to the user, we may want to use the name that the modeler used to introduce this object in the model file. Each EnumeratedObject of a given type also has an index, based on the order in which the objects were introduced in the model file.


public class EnumeratedObject implements Comparable {
    

Creates a new EnumeratedObject of the given type that was introduced with the given name.


    public EnumeratedObject(Type type, int index, NonRandomFunction constant) {
	this.type = type;
	this.index = index;
	this.constant = constant;
    }

    

Returns the non-random constant that canonically stands for this object.


    public NonRandomFunction getConstant() {
	return constant;
    }

    

Returns the name used to introduce this object.


    public String getName() {
	return constant.getName();
    }

    

Returns the index of this object, that is, the number i such that i enumerated objects of this type were introduced before this object in the model file.


    public int getIndex() {
	return index;
    }

    

Returns this object's type.


    public Type getType() {
	return type;
    }

    

Returns this object's name.


    public String toString() {
	return constant.getName();
    }

    

Compares this enumerated object to another one of the same type, based on their indices. Enumerated objects of different types are incomparable.


    public int compareTo(Object o) {
	EnumeratedObject other = (EnumeratedObject) o;
	if (type != other.getType()) {
	    return 0;
	}
	return (index - other.getIndex());
    }

    private Type type;
    private int index;
    private NonRandomFunction constant;
}
