Subject [jira] [Commented] (HBASE-5958) Replace ByteString.copyFrom with new ByteString()
Date Tue, 15 May 2012 17:18:03 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5958?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13276001#comment-13276001

Jimmy Xiang commented on HBASE-5958:

By the way, is it an option to use reflection to access the private constructor? If so, I
can have a wrap method to use the private constructor, or the original copyFrom if the private
constructor is not accessible. Reflection has overhead of course.
