Subject [jira] Issue Comment Edited: (PIG-161) Rework physical plan
Date Mon, 24 Mar 2008 18:51:24 GMT

    [ https://issues.apache.org/jira/browse/PIG-161?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12581637#action_12581637

------------------------------------------------------------------------------

The base classes for the physical operators, the comparison operators, POFilter, POProject,
ConstantExpr, PhysicalPlan, ExprPlan and their corresponding visitors are available in this
patch. This also includes changes to the Operator, OperatorPlan and PlanVisitor to make them
typed. I have checked that it does not affect any previous code. So if people want to use
it they can.

Please feel free to comment.
