      • addMemberConstraint

        public void addMemberConstraint​(SqlQuery sqlQuery,
                                        RolapCube baseCube,
                                        AggStar aggStar,
                                        RolapMember parent)
        Description copied from interface: MemberChildrenConstraint
        Modifies a Member.Children query so that only the children of parent will be returned in the result set.
        Specified by:
        addMemberConstraint in interface MemberChildrenConstraint
        Parameters:
        sqlQuery - the query to modify
        baseCube - base cube for virtual members
        aggStar - Aggregate star, if we are reading from an aggregate table,
        parent - the parent member that restricts the returned children
      • addMemberConstraint

        public void addMemberConstraint​(SqlQuery sqlQuery,
                                        RolapCube baseCube,
                                        AggStar aggStar,
                                        List<RolapMember> parents)
        Description copied from interface: MemberChildrenConstraint
        Modifies a Member.Children query so that (all or some) children of all parent members contained in parents will be returned in the result set.
        Specified by:
        addMemberConstraint in interface MemberChildrenConstraint
        Parameters:
        sqlQuery - Query to modify
        baseCube - Base cube for virtual members
        aggStar - Aggregate table, or null if query is against fact table
        parents - List of parent members that restrict the returned children
      • addLevelConstraint

        public void addLevelConstraint​(SqlQuery query,
                                       RolapCube baseCube,
                                       AggStar aggStar,
                                       RolapLevel level)
        Description copied from interface: MemberChildrenConstraint
        Will be called once for the level that contains the children of a Member.Children query. If the condition requires so, it may join the levels table to the fact table.
        Specified by:
        addLevelConstraint in interface MemberChildrenConstraint
        Parameters:
        query - the query to modify
        baseCube - base cube for virtual members
        aggStar - Aggregate table, or null if query is against fact table
        level - the level that contains the children
      • getCacheKey

        public Object getCacheKey()
        Description copied from interface: SqlConstraint
        Returns a key that becomes part of the key for caching the result of the SQL query. So SqlConstraint instances that produce the same SQL resultset must return equal keys in terms of equal() and hashCode().
        Specified by:
        getCacheKey in interface SqlConstraint
        Returns:
        valid key or null to prevent the result from being cached
