                                                                                 int[] axesMembers,

computeDeepColumnNames

public static void computeDeepColumnNames(org.olap4j.metadata.Member m,
                                          MemberAddingStrategy memberToNameMapping)

Computes a set of column names starting with the deepest parent up to the member actually found on the axis.

Parameters:

m -

computeUniqueColumnName

public static String computeUniqueColumnName(org.olap4j.Position p)

Column axis members can be nested (having multiple dimensions or multiple levels of the same dimension) and thus the Member's unique name is not necessarily unique across the whole context (same year mentioned for different product lines, for example). So we need to compute that name recursively.

Parameters:

p - The OLAP position, a list of members uniquely specifying a cell-position.

Returns:

the computed name, usually jus a concat of all levels.
