Method Detail
-
getWeight
double getWeight(String attributeName) throws NameNotFoundException
- Returns:
- double the weight of the given attribute. If the weight is not set, the default weight 1.0 will be returned.
- Throws:
NameNotFoundException
-
setWeight
void setWeight(String attributeName, double weight) throws NameNotFoundException
- Parameters:
attributeName
- is the name of the attribute whos weight should be setweight
- is the weight of the attribute. The values will normalized automatically.- Throws:
NameNotFoundException
- if the attribute not exists
-
getDefaultWeight
double getDefaultWeight()
- Returns:
- default weight
-
setDefaultWeight
void setDefaultWeight(double weight)
- Parameters:
weight
- is the default weight for each attribute, which hasn't an own weight
