    • Method Detail

      • getCaptionValue

        public Object getCaptionValue()
        An object value to be formatted further by member formatter. Actually, acts like MemberBase#getCaption(), but using not formatted object values.

      • getOrdinal

        public int getOrdinal()
        Description copied from class: MemberBase
        Returns the ordinal of this member within its hierarchy. The default implementation returns -1.
        Specified by:
        getOrdinal in interface Member
        Overrides:
        getOrdinal in class MemberBase

      • setOrdinal

                          boolean forced)

      • isHidden

        public boolean isHidden()
        Description copied from interface: Member
        Returns whether this member is 'hidden', as per the rules which define a ragged hierarchy.
        Specified by:
        isHidden in interface Member
        Overrides:
        isHidden in class MemberBase

      • getDepth

        public int getDepth()
        Description copied from interface: Member
        returns the depth of this member, which is not the level's depth in case of parent child dimensions
        Specified by:
        getDepth in interface Member
        Returns:
        depth

      • getAllMembers

        public static List<List<Member>> getAllMembers​(SchemaReader schemaReader,
                                               Hierarchy hierarchy)
        Returns a list of member lists where the first member list is the root members while the last member array is the leaf members.

        If you know that you will need to get all or most of the members of a hierarchy, then calling this which gets all of the hierarchy's members all at once is much faster than getting members one at a time.

        Parameters:
        schemaReader - Schema reader
        hierarchy - Hierarchy
        Returns:
        List of arrays of members

      • getHierarchyCardinality

        public static int getHierarchyCardinality​(SchemaReader schemaReader,
                                          Hierarchy hierarchy)

      • setOrdinals

        public static void setOrdinals​(SchemaReader schemaReader,
                               Member seedMember)
        Sets member ordinal values using a Bottom-up/Top-down algorithm.

        Gets an array of members for each level and traverses array for the lowest level, setting each member's parent's parent's etc. member's ordinal if not set working back down to the leaf member and then going to the next leaf member and traversing up again.

        The above algorithm only works for a hierarchy that has all of its leaf members in the same level (that is, a non-ragged hierarchy), which is the norm. After all member ordinal values have been set, traverses the array of members, making sure that all members' ordinals have been set. If one is found that is not set, then one must to a full Top-down setting of the ordinals.

        The Bottom-up/Top-down algorithm is MUCH faster than the Top-down algorithm.

        Parameters:
        schemaReader - Schema reader
        seedMember - Member

      • keyToString

        protected static String keyToString​(Object key)
        Converts a key to a string to be used as part of the member's name and unique name.

        Usually, it just calls Object.toString(). But if the key is an integer value represented in a floating-point column, we'd prefer the integer value. For example, one member of the [Sales].[Store SQFT] dimension comes out "20319.0" but we'd like it to be "20319".

        Returns the solve order of this calculation. Identifies which order calculations are expanded.
        Returns:
