org.apache.druid.math.expr.ExprListenerImpl

All Implemented Interfaces:

org.antlr.v4.runtime.tree.ParseTreeListener, ExprListener

public class ExprListenerImpl
extends ExprBaseListener

Implementation of antlr parse tree listener, transforms ParseTree to Expr, based on the grammar defined in Expr.g4. All Expr are created on 'exit' so that children Expr are already constructed.
