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 set

weight - 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
