Subject [jira] Created: (LUCENE-1680) Make prefixLength accessible to PrefixTermEnum subclasses
Date Wed, 10 Jun 2009 08:31:08 GMT
Make prefixLength accessible to PrefixTermEnum subclasses
---------------------------------------------------------

                 Key: LUCENE-1680
                 URL: https://issues.apache.org/jira/browse/LUCENE-1680
             Project: Lucene - Java
          Issue Type: Improvement
    Affects Versions: 2.9
            Reporter: Simon Willnauer
             Fix For: 2.9
         Attachments: PrefixTermEnum.patch

PrefixTermEnum#difference() offers a way to influence scoring based on the difference between
the prefix Term and a term in the enumeration. To effectively use this facility the length
of the prefix should be accessible to subclasses. Currently the prefix term is private to
PrefixTermEnum. I added a getter for the prefix length and made PrefixTermEnum#endEnum(),
PrefixTermEnum#termCompare() final for consistency with other TermEnum subclasses.

Patch is attached.

Simon
