Subject [jira] Commented: (LUCENE-1796) Speed up repeated TokenStream init
Date Mon, 10 Aug 2009 16:38:14 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1796?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12741416#action_12741416
] 

Uwe Schindler commented on LUCENE-1796:
---------------------------------------

Mark: The only hotspot could be initTokenWrapper(), which does some checks, but normally shortcuts
in filters to the input TokenStream's TokenWrapper instance.

Using incrementToken() would not help here, only if you switch of using the old API complete
using TokenStream.setOnlyUseNewAPI(true), which can only be done globally, so all Solr TokenStreams
must implement incrementToken().
