---------------------------------
Summary: Add missing visitor methods of AlgebraVisitor and
BaseAlgebraVisitor
Key: TAJO-419
URL: https://issues.apache.org/jira/browse/TAJO-419
Project: Tajo
Issue Type: Improvement
Components: parser, planner/optimizer
Reporter: Hyunsik Choi
Assignee: Hyunsik Choi
Fix For: 0.8-incubating
This patch primarily adds all missing operator types' visitor methods of
AlgebraVisitor and implements concrete methods in BaseAlgebraVisitor.
Currently, BaseAlgebraVisitor may cause incorrect PlanningException because
BaseAlgebraVisitor does not handle all operator types. This patch eliminates
this potential bug.
In addition, this patch contains two refactors in order to eliminate duplicate
names:
* Rename tajo.algebra.DataType to DataTypeExpr
* Rename tajo.algebra.Target to TargetExpr
