public interface Filter<T>

The object interface is used by processes wishing to process data objects that match a defined filter. The following example shows the typical use of filters.

   public void process(List objects) {
     for (Iterator iter = objects.iterator; iter.hasNext();; ) {
       Record object = (Record)iter.next();
       if (filter.accept(object) {
         // perform action
       }
     }
   }
