Description copied from class: Function

Override this method to check conditions on the arguments (like types) passed to the function in apply before the operate method is called. Throw the declared exception with a meaningful message when condition are not met. Note: Number of arguments < arity is checked before this is called to have enough arguments to operate on, however if more is no good, check it here ... Default implementation does nothing.
