Eks Dev updated LUCENE-1219:
----------------------------
Attachment: LUCENE-1219.patch
this one keeps addition of new methods localized to AbstractField, does not
change Fieldable interface... it looks like it could work done this way with a
few instanceof checks in FieldsWriter, This one has dependency on LUCENE-1217
it will not give you any benefit if you directly implement your Fieldable
without extending AbstractField, therefore I would suggest to eventually
change Fieldable to support all these methods that operate with offset/length.
Or someone clever finds some way to change an interface without braking
backwards compatibility :)
> support array/offset/ length setters for Field with binary data

>
> currently Field/Fieldable interface supports only compact, zero based byte
> arrays. This forces end users to create and copy content of new objects
> before passing them to Lucene as such fields are often of variable size.
> Depending on use case, this can bring far from negligible performance
> improvement.
> this approach extends Fieldable interface with 3 new methods
> getOffset(); gettLenght(); and getBinaryValue() (this only returns reference
> to the array)
