Erik,
I got a bit out of sync with the CVS build (because it took a while to
integrate the changes), so I can't quickly do a simple diff. Instead, I'm
including the changed methods in HitsIterator in this message verbatim. Not
real pretty code, I know, but it does work just fine.
Regards and HTH,
Terry
Note: direction can be 'r', 'a' or 'd' (default)
public HitsIterator(Hits hits, String sortField, String direction) throws
IOException{
this.hitsCollection = hits;
if (sortField != null){
if ((direction != null) && (!direction.equals("r"))){
sortByField(sortField, direction);
}
}
totalHits = getTotalHits();
setPageCount();
}
private void sortByField(String fieldName, String direction) throws
IOException{
long start = System.currentTimeMillis();
Comparator c = null;
if (fieldName == null){
return;
}
SortedField sf = SortedField.getSortedField(fieldName);
int dirflag = -1;
if(direction.equals("a")) {
dirflag = 1;
} else if(direction.equals("r")) {
dirflag = 0;
}
if (sf !=null){
c = (Comparator) new CompareDocumentsByField(dirflag);
} else {
arrayOfIndividualHits = null;
return;
}
int i = 0;
int id = 0;
String fv = null;
try{
arrayOfIndividualHits = new Object[hitsCollection.length()];
long first = System.currentTimeMillis();
for (i=0; i<hitsCollection.length(); i++) {
id = hitsCollection.id(i);
try {
fv = sf.getFieldValue(id);
} catch (Exception e) {
fv = null;
}
if(fv != null && fv.length() > 0) {
arrayOfIndividualHits[i] = new IndividualHit(i, fv,
hitsCollection.score(i));
fv = null;
}
}
} catch (Exception e) {
msg("Error ["+fv+"]:"+e);
}
long second = System.currentTimeMillis();
Arrays.sort(arrayOfIndividualHits, c);
}
