Class MqlNode

java.lang.Object
  antlr.BaseAST
      antlr.CommonAST
          org.makumba.providers.query.mql.MqlNode

All Implemented Interfaces:

antlr.collections.AST, Serializable

Direct Known Subclasses:

MqlBinaryOperator, MqlDotNode, MqlIdentNode

public class MqlNode
extends antlr.CommonAST

The root of Mql analysis tree nodes. It performs analysis as the tree is built. It should know how to determine its Makumba type, if it is not a parameter.
