Class IconFactory.SizeComperator

java.lang.Object
  uic.model.IconFactory.SizeComperator

All Implemented Interfaces:

Comparator

Enclosing class:

IconFactory

public static class IconFactory.SizeComperator

extends Object

implements Comparator

This comperator is usable to sort image sizes in an existing collection for best quality. Most icon libraries have icons of different sizes and when a size requested does not return a image we have to look further for almost matches.

For a list of sizes (as Number objects in a collection) this Comparator can be used to return a sorted list where the best matching size comes first and the worst matching comes last.

After sorting its a case of trying each item in the collection for a match.

Example usage:

      List myList = new Vector();
      myList.add(new Integer(22));
      myList.add(new Integer(128));
      myList.add(new Integer(48));
      Collections.sort(myList, new SizeComperator(preferredSize));
      Iterator iter = myList.iterator();
      while(iter.hasNext()) {
          Integer integer = (Integer) iter.next();
          // search for icon in dir the represents 'integer' size.
      }
