public void setAllele(Attribute r)

Sets the lower and upper values.

Specified by:

setAllele in interface Attribute

Parameters:

r - is the realRep of the classifier that has to be copied.

getAttributeAllele

public Attribute getAttributeAllele()

Returns the value of the alelle

Specified by:

getAttributeAllele in interface Attribute

Returns:

a 2RealRep with the two reals numbers of the representation.

getLowerAllele
