Returns:

the Concept stored as the To-Concept in this Projection

setFromConcept

void setFromConcept(Concept fromConcept)
                    throws M4Exception

Setter method for the From-Concept of this Projection

Parameters:

fromConcept - the Concept to be set as the new From-Concept

Throws:

M4Exception

setToConcept

void setToConcept(Concept toConcept)
                  throws M4Exception

Setter method for the To-Concept of this Projection

Parameters:

toConcept - the Concept to be set as the new To-Concept

Throws:

M4Exception

isValid

boolean isValid()
                throws M4Exception

For a valid projection, the From concept must have all the features of the To concept (correspondence is determined by name), and can have more.
