    • instance

      public static SqlConstraintFactory instance()

    • setNativeNonEmptyValue

      public static void setNativeNonEmptyValue()

    • getMemberChildrenConstraint

      public MemberChildrenConstraint getMemberChildrenConstraint(Evaluator context)

    • getLevelMembersConstraint

      public TupleConstraint getLevelMembersConstraint(Evaluator context)

    • getLevelMembersConstraint

      public TupleConstraint getLevelMembersConstraint(Evaluator context, Level[] levels)
      Returns a constraint that restricts the members of a level to those that are non-empty in the given context. If the constraint cannot be implemented (say if native constraints are disabled) returns null.
      Parameters:
      context - Context within which members must be non-empty
      levels - levels being referenced in the current context
      Returns:
      Constraint

    • getChildByNameConstraint

      public MemberChildrenConstraint getChildByNameConstraint(RolapMember parent, Id.NameSegment childName)

    • getChildrenByNamesConstraint

      public MemberChildrenConstraint getChildrenByNamesConstraint(RolapMember parent, List<Id.NameSegment> childNames)

    • getDescendantsConstraint

      public TupleConstraint getDescendantsConstraint(List<RolapMember> parentMembers, MemberChildrenConstraint mcc)
      Returns a constraint that allows to read all children of multiple parents at once using a LevelMember query style. This does not work for parent/child hierarchies.
      Parameters:
      parentMembers - List of parents (all must belong to same level)
      mcc - The constraint that would return the children for each single parent
      Returns:
      constraint
