[Biojava-l] Sort symbols in an alphabet

[Ren, Zhen]

A copy of the symbol set in an alphabet is sorted.  What if I want to sort the original symbol set in an alphabet?  Thanks. -Zhen

The following code should do it,

You could actually make the ComparableSymbol wrapper implement Symbol
and pass all the Symbol methods directly to the wrapped Symbol. I may
even submit a ComparableSymbol as a class to biojava-live if people
think they would use it.

import org.biojava.bio.seq.*;
import org.biojava.bio.symbol.*;
import java.util.*;

public class SortAlphabetByName {
  public static void main(String[] args) {
    List l = new ArrayList();

    //add Symbols out of order
    l.add(new ComparableSymbol(DNATools.c()));
    l.add(new ComparableSymbol(DNATools.g()));
    l.add(new ComparableSymbol(DNATools.t()));
    l.add(new ComparableSymbol(DNATools.a()));

    //sort them
    Collections.sort(l);

    //print there names
    for (int i = 0; i < l.size(); i++) {
      ComparableSymbol cs = (ComparableSymbol)l.get(i);
      System.out.println(cs.getWrapped().getName());
    }

  }

  // a Mix in wrapper
  static class ComparableSymbol implements Comparable{
    private Symbol wrapped;

    public ComparableSymbol(Symbol wrapped){
      this.wrapped = wrapped;
    }

    public int compareTo(Object o){
      Symbol s = ((ComparableSymbol)o).getWrapped();

      return wrapped.getName().compareTo(s.getName());
    }

    public Symbol getWrapped(){
      return wrapped;
    }
  }
}
