Hi,
Thank you. I implements the iterator interface, and now it is working.
public class SearchResults implements Iterator<SearchResult> {
private Set<String> keySet = null;
private Iterator<String> iterator = null;
private Set<String> keySet() {
if (this.keySet == null) {
this.keySet = this.results.keySet();
}
return this.keySet;
}
private Iterator<String> iterator() {
if (this.iterator == null){
this.iterator = this.keySet().iterator();
}
return this.iterator;
}
public SearchResult get(String key) {
return this.results.get(key);
}
@Override
public boolean hasNext() {
return this.iterator().hasNext();
}
@Override
public SearchResult next() {
String next = this.iterator().next();
return this.get(next);
}
}
Calls (hasNext() and next()) are done in org.apache.struts2.components.
IteratorComponent
Thanks
Matthieu MARC
