Alphabets are, by design, pretty straigforward sets of symbol
objects. If you want to print them out in some specific order,
how about:
FiniteAlphabet fa = ...
List faSymbols = new ArrayList();
for (Iterator i = fa.iterator(); i.hasNext(); ) {
faSymbols.add(i.next());
}
Collections.sort(
faSymbols,
new Comparator() {
public int compare(Object o1, Object o2) {
Symbol s1 = (Symbol) o1;
Symbol s2 = (Symbol) o2;
return s1.getName().compareTo(s2.getName());
}
}
);
