Class ProductLatticeDerivedConceptFunction

ptolemy.data.ontologies.lattice.ProductLatticeDerivedConceptFunction

public class ProductLatticeDerivedConceptFunction
extends ConceptFunction

A concept function that returns a derived concept from a given input concept for a product lattice ontology to be used for constraints generated from an ontology that is a component of the product lattice ontology. Whatever the input product lattice concept is, the output is a product lattice concept whose tuple preserves the value of the concept in the given component ontology, but sets the other concepts in the tuple to the bottom of their respective ontology lattices. This is used for constraints that are derived from the lattice ontology adapters of ontologies that comprise the product lattice ontology, so that their constraints are orthogonal to the other ontologies in the product lattice ontology.

ProductLatticeDerivedConceptFunction

public ProductLatticeDerivedConceptFunction(java.lang.String name,
                                            ProductLatticeOntology inputOutputOntology,
                                            Ontology originalConceptOntology)
                                     throws IllegalActionException

Create a new ProductLatticeDerivedConceptFunction with the given name, derived from the given original component ontology.

Parameters:

name - The name of the derived concept function.

inputOutputOntology - The ProductLatticeOntology for the derived function.

originalConceptOntology - The original ontology for the original concept input.

Throws:

IllegalActionException - Thrown if the wrapper concept function cannot be created.

Method Detail

_evaluateFunction

protected Concept _evaluateFunction(java.util.List<Concept> argValues)
                             throws IllegalActionException

Return the output of the concept function based on the concept inputs. Whatever the input product lattice concept is, the output is a product lattice concept whose tuple preserves the value of the concept in the given component ontology, but sets the other concepts in the tuple to the bottom of their respective ontology lattices.

Specified by:

_evaluateFunction in class ConceptFunction

Parameters:

argValues - The list of concept inputs to the function.

Returns:

The concept output result of the function.

Throws:

IllegalActionException - If there is an error evaluating the function.
