org.makumba.providers.query.mql
Class MqlSqlWalker

java.lang.Object
  extended by antlr.TreeParser
      extended by org.makumba.providers.query.mql.MqlSqlBaseWalker
          extended by org.makumba.providers.query.mql.MqlSqlWalker
All Implemented Interfaces:
HqlSqlTokenTypes
public class MqlSqlWalker
extends MqlSqlBaseWalker

Analysis operations. This extends the class produced by mql-sql.g which is adapted from Hibernate. To simplify porting of new versions, the class mostly redefines methods declared in mql-sql.g.
