Hi there,
I'm currently trying to work out how I can determine the type
(string/number/date/etc)of a term. I've not seen any off the shelf way to do
it so am trying to store a payload against each term that records the type.
I'm having a little trouble retrieving a payload I'd stored onto the term. At
the moment I'm using the TypeAsPayloadTokenFilter, however I'll change this
soon as it's not really what I'm after.
I'm then getting a TermEnum from either reader.terms() or using a
PrefixTermEnum.
For each term I want the payload from I'm running this function:
private String getPayload(Term term) {
String payload = null;
try {
TermPositions termPositions = reader.termPositions(term);
termPositions.next();
if (termPositions.isPayloadAvailable()) {
byte[] payloadBytes = new
byte[termPositions.getPayloadLength()];
payloadBytes = termPositions.getPayload(payloadBytes, 0);
payload = new String(payloadBytes);
LOG.debug(payload);
}
}
catch( IOException e) {
...
This never returns anything though.
Am I missing something here? Any help would be greatly appreciated.
Cheers,
Derek
