Class ExprAnnotator

java.lang.Object

org.apache.tajo.plan.algebra.BaseAlgebraVisitor<org.apache.tajo.plan.ExprAnnotator.Context,EvalNode>

org.apache.tajo.plan.ExprAnnotator

All Implemented Interfaces:

AlgebraVisitor<org.apache.tajo.plan.ExprAnnotator.Context,EvalNode>

public class ExprAnnotator
extends BaseAlgebraVisitor<org.apache.tajo.plan.ExprAnnotator.Context,EvalNode>

ExprAnnotator makes an annotated expression called EvalNode from an Expr. It visits descendants recursively from a given expression, and finally it returns an EvalNode.
