[jira] [Created] (LUCENE-7419) performance bug in tokenstream.end()

Robert Muir created LUCENE-7419:
-----------------------------------

             Summary: performance bug in tokenstream.end()
                 Key: LUCENE-7419
                 URL: https://issues.apache.org/jira/browse/LUCENE-7419
             Project: Lucene - Core
          Issue Type: Bug
            Reporter: Robert Muir


TokenStream.end() calls getAttribute(), which is pretty costly to do per-stream.

It does its current hack, because in the ctor of TokenStream is "too early".

Instead, we can just add a variant of clear(), called end() to AttributeImpl. For most attributes it defers to clear, but for PosIncAtt it can handle the special case.
