public abstract class BothfixSyntax
extends PostfixSyntax
implements PrefixSyntaxInterface

This class represents bothfix syntax, that which can be both prefix and postfix, depending on the situation. This is a convenience class to reduce the work required to implement a syntax that is both prefix and postfix. It may be that the syntax has different meanings in prefix vs. postfix form.
