LUCENE-5670: add skip/FinalOutput to FST Outputs
> org.apache.lucene.util.fst.FST should skip over outputs it is not interested
> in
> -------------------------------------------------------------------------------
>
> Key: LUCENE-5670
> URL: https://issues.apache.org/jira/browse/LUCENE-5670
> Project: Lucene - Core
> Issue Type: Improvement
> Affects Versions: 4.7
> Reporter: Christian Ziech
> Assignee: Michael McCandless
> Priority: Minor
> Fix For: 4.9, 5.0
>
> Attachments: LUCENE-5670.patch, skipOutput_lucene48.patch
>
>
> Currently the FST uses the read(DataInput) method from the Outputs class to
> skip over outputs it actually is not interested in. For most use cases this
> just creates some additional objects that are immediately destroyed again.
> When traversing an FST with non-trivial data however this can easily add up
> to several excess objects that nobody actually ever read.
