  • All Implemented Interfaces:
    Function
    Enclosing class:
    FactorOracle
    protected class FactorOracle.ChordFunction
extends java.lang.Object
implements Function
    A function that evaluates to true if the "pitch" that would be produced as a result of taking this transition satisfies chord specifications. In the current application, the specifications are given by MusicSpecs.getChordPitches(String, boolean).

      • apply

        public Token apply​(Token[] arguments)
            throws IllegalActionException
        Description copied from interface: Function
        Apply the function to the list of arguments, which are tokens.
        Specified by:
        apply in interface Function
        Parameters:
        arguments - The list of arguments.
        Returns:
        The result of applying the function to the given arguments.
        Throws:
        IllegalActionException - If thrown during evaluating the function.

        public int getNumberOfArguments()
        Description copied from interface: Function
        Return the number of arguments of the function.
        Specified by:
        getNumberOfArguments in interface Function
        Returns:
        The number of arguments of the function.

      • isCongruent

        public boolean isCongruent​(Function function)
        Description copied from interface: Function
        Return true if this function is congruent to the given function. Classes should implement this method so that two functions are congruent under any renaming of the bound variables of the function. For simplicity, a function need only be congruent to other functions of the same class.
        Specified by:
        isCongruent in interface Function
        Parameters:
        function - The function to check congruency against.
        Returns:
        True if this function is congruent with the given function.

        Description copied from interface: Function
        Return a string representation.
        Specified by:
        toString in interface Function
        Overrides:
        toString in class java.lang.Object
        Returns:
        A string representation of this function.
