Subject [jira] Updated: (LUCENE-937) Make CachingTokenFilter faster
Date Fri, 22 Jun 2007 14:38:26 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-937?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mark Miller updated LUCENE-937:
-------------------------------

      Description: The LinkedList used by CachingTokenFilter is accessed using the get() method.
Direct access on a LinkedList is slow and an Iterator should be used instead. For more than
a handful of tokens, the difference in speed grows exponentially.  (was: The wrong data structure
was used for the CachingTokenFilter. It should be an ArrayList rather than a LinkedList. There
is a noticeable difference in speed.)
    Lucene Fields: [New, Patch Available]  (was: [Patch Available, New])
