Joel Bernstein commented on SOLR-9720:
--------------------------------------
This is quite nice:
{code}
+ public Map toMap(Map<String, Object> map) {
+ try {
+ if (!isOpen) {
+ open();
+ isOpen = true;
+ }
+ } catch (IOException e) {
+ throw new SolrException(SolrException.ErrorCode.SERVER_ERROR, e);
+ }
+ return Collections.singletonMap("docs", new Iterator<Tuple>() {
+ Tuple tuple;
+ boolean isEOF = false;
+
+ @Override
+ public boolean hasNext() {
+ if (isEOF) return false;
+ if (tuple != null) return true;
+ try {
+ tuple = read();
+ if(tuple != null && tuple.EOF) close();
+ return tuple != null;
+ } catch (IOException e) {
+ throw new SolrException(SolrException.ErrorCode.SERVER_ERROR, e);
+ }
+ }
+
+ @Override
+ public Tuple next() {
+ Tuple tmp = tuple;
+ tuple = null;
+ isEOF = tmp == null || tmp.EOF;
+ return tmp;
+ }
+ });
}
{code}
