Constructor Detail

ConceptFunctionInequalityTerm

public ConceptFunctionInequalityTerm(ConceptFunction conceptFunction,
                                     InequalityTerm[] inputTerms)
                              throws IllegalActionException

Initialize the inequality term with the ConceptFunction it refers to and the array of inequality terms that are inputs to the function.

Parameters:

conceptFunction - The concept function to be called to get the value for this inequality term.

inputTerms - The array of inequality term inputs to the concept function.

Throws:

IllegalActionException - If the number of input terms does not match the required number of arguments for the concept function.

Method Detail

getAssociatedObject

public java.lang.Object getAssociatedObject()

Return the concept function associated with this concept function inequality term.

Specified by:

getAssociatedObject in interface InequalityTerm

Returns:

The concept function evaluated by this concept function inequality term.

getConstants

public final InequalityTerm[] getConstants()

Return an array of constants contained in this term. Since this term represents a function, return an array containing all the Concept constants in the function.

Returns:

An array of InequalityTerms

getDependentTerms

public final InequalityTerm[] getDependentTerms()

Return the array of dependent terms contained by this term. For a ConceptFunctionInequalityTerm, these terms represent the input arguments to the concept function in the order they are passed to the function.

Returns:

An array of InequalityTerms that represent the dependent terms.

getValue

public java.lang.Object getValue()
                          throws IllegalActionException

Return the value of this inequality term. Since this term is for a concept function, return the evaluation of the concept function based on the current values of variables passed into the function.

Specified by:

getValue in interface InequalityTerm

Returns:

An Object representing an element in the underlying CPO.

Throws:

IllegalActionException - If the value of this inequality term is not valid.

See Also:

setValue(Object)

getVariables

public final InequalityTerm[] getVariables()

Return the concept variables for this inequality term. This method returns an array of InequalityTerms that the concept function referred to by this ConceptFunctionInequalityTerm depends on.

Specified by:

getVariables in interface InequalityTerm

Returns:

An array of InequalityTerms.

initialize

public final void initialize(java.lang.Object e)
                      throws IllegalActionException

Throw an Exception. This method cannot be called on a function term.

Specified by:

initialize in interface InequalityTerm

Parameters:

e - The object value used to initialize the inequality term. Since this method always throws an exception, this parameter is never used.

Throws:

IllegalActionException - Always thrown.

isSettable

public final boolean isSettable()

Return false. Concept function terms are not settable.

Specified by:

isSettable in interface InequalityTerm

Returns:

False.

isValueAcceptable

public boolean isValueAcceptable()

Return true. Function terms are, by default, always acceptable.

Specified by:

isValueAcceptable in interface InequalityTerm

Returns:

True.

setValue

public final void setValue(java.lang.Object e)
                    throws IllegalActionException

Throw an Exception. The value of a function term cannot be set.

Specified by:

setValue in interface InequalityTerm

Parameters:

e - The object value to set the inequality term. Since this method always throws an exception, this parameter is never used.

Throws:

IllegalActionException - Always thrown.

getValue()

toString

public java.lang.String toString()

Override the base class to give a description of this term.

Overrides:

toString in class java.lang.Object

Returns:

A description of this term.
