Subject [jira] Commented: (PIG-158) Rework logical plan
Date Thu, 03 Apr 2008 22:33:24 GMT

    [ https://issues.apache.org/jira/browse/PIG-158?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12585325#action_12585325

Pi Song commented on PIG-158:
-----------------------------

Classic visitor = Walker logic + Event Handler + State management 

Visitor to me has too much responsibilities so I suggested before to do it SAXParser style.
In this case it is sensible to store state in walker.
