Method Detail

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.

getNumberOfArguments

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.

toString

public java.lang.String toString()

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.
