Constructor Detail

ArtificialConcept

public ArtificialConcept(Network network,
                         String name)

TODO: Raise exception if conceptSet already exists as a key in conceptArea.

Parameters:

network - a Network value

conceptSet - a Vector value

Method Detail

getConceptSet

public Set getConceptSet()
