Dawid Weiss reassigned LUCENE-5372: ----------------------------------- Assignee: Dawid Weiss > IntArray toString has O(n^2) performance > ---------------------------------------- > > Key: LUCENE-5372 > URL: https://issues.apache.org/jira/browse/LUCENE-5372 > Project: Lucene - Core > Issue Type: Bug > Components: core/index > Reporter: Joshua Hartman > Assignee: Dawid Weiss > Priority: Minor > Fix For: 5.0, 4.7 > > Attachments: 5372.patch > > > This is pretty minor, but I found a few issues with the toString > implementations while looking through the facet data structures. > The most egregious is the use of string concatenation in the IntArray class. > I have fixed that using StringBuilders. I also noticed that other classes > were using StringBuffer instead of StringBuilder. According to the javadoc, > "This class is designed for use as a drop-in replacement for StringBuffer in > places where the string buffer was being used by a single thread (as is > generally the case). Where possible, it is recommended that this class be > used in preference to StringBuffer as it will be faster under most > implementations." -- This message was sent by Atlassian JIRA (v6.1.4#6159) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
