Checks whether this attribute description can override the given attribute description

Specified by:

canOverride in class SimpleAttDesc

fits

public boolean fits(Attribute att)

Description copied from class: AttributeDesc

Checks whether the given attribute fits this. Be aware that if this is multiple then single values will not fit. For checking whether single values fit this description without taking multiple values into account call AttributeDesc.fitsSingle(Attribute)
