Examples of org.apache.lucene.util.AttributeSource.copyTo()

org.apache.lucene.util.AttributeSource.copyTo()
Copies the contents of this {@code AttributeSource} to the given target {@code AttributeSource}. The given instance has to provide all {@link Attribute}s this instance contains. The actual attribute implementations must be identical in both {@code AttributeSource} instances;ideally both AttributeSource instances should use the same {@link AttributeFactory}. You can use this method as a replacement for {@link #restoreState}, if you use {@link #cloneAttributes} instead of {@link #captureState}.

        clearAttributes();
        AttributeSource next = tokenIterator.next();
        Iterator<Class<? extends Attribute>> atts = next.getAttributeClassesIterator();
        while (atts.hasNext()) // make sure all att impls in the token exist here
          addAttribute(atts.next());
        next.copyTo(this);
        return true;
      } else {
        return false;
      }
    }
