Interface RolapCubeHierarchy.RolapCubeHierarchyMemberReader

    • Method Detail

      • getLeadMember

        RolapMember getLeadMember​(RolapMember member,
                                  int n)
        Returns the member n after member in the same level (or before, if n is negative). Returns Hierarchy.getNullMember() if we run off the beginning or end of the level.
      • compare

        int compare​(RolapMember m1,
                    RolapMember m2,
                    boolean siblingsAreEqual)
        Compares two members according to their order in a prefix ordered traversal. If siblingsAreEqual, then two members with the same parent will compare equal.
        Returns:
        less than zero if m1 occurs before m2, greater than zero if m1 occurs after m2, zero if m1 is equal to m2, or if siblingsAreEqual and m1 and m2 have the same parent
      • getMemberChildren

        Map<? extends Member,​Access> getMemberChildren​(RolapMember member,
                                                             List<RolapMember> children,
                                                             MemberChildrenConstraint constraint)
        Populates a list of the children of a Member, optionally applying a constraint.
        Parameters:
        member - Members whose children to find
        children - List to populate with members
        constraint - Constraint
        Returns:
        After populating the list passed as an argument, this method returns a map of the members it just populated along with the Access information applicable. If no access control applies to the member, the map will contain null values.
      • getMemberChildren

        Map<? extends Member,​Access> getMemberChildren​(List<RolapMember> parentMembers,
                                                             List<RolapMember> children,
                                                             MemberChildrenConstraint constraint)
        Populates a list of the children of a given set of Members, optionally applying a constraint.
        Parameters:
        parentMembers - List of members whose children to find
        children - List to populate with members
        constraint - Constraint
        Returns:
        After populating the list passed as an argument, this method returns a map of the members it just populated along with the Access information applicable. If no access control applies to the member, the map will contain null values.
      • getMembersInLevel

        List<RolapMember> getMembersInLevel​(RolapLevel level,
                                            TupleConstraint constraint)
        Returns the members in the given Level, optionally applying a constraint.
        Parameters:
        level - Level
        constraint - Constraint
        Returns:
        list of members
      • getLevelMemberCount

        int getLevelMemberCount​(RolapLevel level)
        Returns the number of members in this level.
        Parameters:
        level - Level
        Returns:
        number of members in level
      • substitute

        RolapMember substitute​(RolapMember member)
        Substitutes a given member. If member is null, returns null.

        This method is called whenever a member is returned from the wrapped member reader and is to be returned to the caller. You could say that it translates 'to caller space'.

        Parameters:
        member - Member
        Returns:
        Substitute member
      • desubstitute

        RolapMember desubstitute​(RolapMember member)
        Returns the member which was substituted. If member is null, returns null.

        This method is called whenever the caller passes a member into a method and needs to be passed to a method on the wrapped member reader. You could say that it translates 'from caller space'.

        Parameters:
        member - Member
        Returns:
        Internal member
      • getMemberByKey

        RolapMember getMemberByKey​(RolapLevel level,
                                   List<Comparable> keyValues)
        Looks up a member by its key value.
        Parameters:
        level - Level
        keyValues - Key values
        Returns:
        Member, or null
