Examples of ScalarVisitor

org.apache.pig.newplan.logical.visitor.ScalarVisitor
Logical plan visitor which handles scalar projections. It will find or create a LOStore and a soft link between the store operator to a scalar expression. It will also sync the file name between the store and scalar expression.

Examples of org.apache.pig.newplan.logical.visitor.ScalarVisitor

        QueryParserDriver parserDriver = new QueryParserDriver( pc, "test", fileNameMap );
        org.apache.pig.newplan.logical.relational.LogicalPlan lp = parserDriver.parse( query );
        
        new ColumnAliasConversionVisitor( lp ).visit();
        new SchemaAliasVisitor( lp ).visit();
        new ScalarVisitor(lp, pc, "test").visit();
        
        CompilationMessageCollector collector = new CompilationMessageCollector() ;
        
        new TypeCheckingRelVisitor( lp, collector).visit();
