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.
