       [Promotion Media].[Sunday Paper],
       [Promotion Media].[Street Handout] },
     [Product].[Drink].children) on rows

    • setName

      public void setName(String newName)
      Sets string attribute name, which identifies this query within its page. The <transform query> attribute uses this.

    • getName

      public String getName()

    • setResultCache

      public void setResultCache(boolean newResultCache)
      Sets boolean attribute resultCache; if true, the query is parsed, executed, and converted to an XML document at most once. This improves performance and consistency, but the results may become out of date. We also need a way to prevent the cache using too much memory.

    • isResultCache

      public boolean isResultCache()
