Method Detail

filter

Iterator filter(Iterator src,
                Object context)

The filter method is provided to allow the creation of the filtering iterator.

Any implementation should follow the following pattern:

  public Iterator filter(Iterator src, Object context) {
                return new Filterator(src, context, this);
        }
  

This pattern makes the source iterator, the evaluation context, and the IPropertySet annotations visible to the runtime striterator implementation.
