Examples of ProjStarInUdfExpander

org.apache.pig.newplan.logical.visitor.ProjStarInUdfExpander
Expand project-star or project-range when used as udf argument. This is different from {@link ProjectStarExpander} because in those cases, the project star gets expanded as new {@link LogicalExpressionPlan}. In case of project-star or project-range within udf, it should get expanded only as multiple inputs to this udf, no addtional {@link LogicalExpressionPlan}s are created. The expansion happens only if input schema is not null
