All Implemented Interfaces:
Serializable

    • isRequireOuterJoins

      public boolean isRequireOuterJoins()
      Return the current 'mode' indicating if outer joins are currently required or not.

    • setRequireOuterJoins

      public void setRequireOuterJoins(boolean requireOuterJoins)
      Set the 'mode' to be that joins added are required to be outer joins. This is set during the evaluation of disjunction predicates.

    • add

      public void add(ElPropertyDeploy elProp)
      Add a many where join.

    • requireSqlDistinct

      public boolean requireSqlDistinct()
      Return true if this is an aggregation query or if there are no extra many where joins.

    • propertyJoins

      public Collection<PropertyJoin> propertyJoins()
      Return the set of many where joins.

    • propertyNames

      public TreeSet<String> propertyNames()
      Return the set of property names for the many where joins.

    • addFormulaWithJoin

      public void addFormulaWithJoin(String prefix, String name)
      In findCount query found a formula property with a join clause so building a select clause specifically for the findCount query.

    • isFormulaWithJoin

      public boolean isFormulaWithJoin(String prefix)
      Return true if the query select includes a formula with join.

    • formulaJoinProperties

      public List<String> formulaJoinProperties(String prefix)
      Return the formula properties to build the select clause for a findCount query.

    • setAggregation

      public void setAggregation()
      Mark this as part of an aggregation query (so using group by clause).

    • addAggregationJoin

      public void addAggregationJoin(String property)
      Ensure we have the join required to support the aggregation properties.
