public class VersionHistoryColumnInfo
extends ComplexColumnInfo<Version>

Complex column info for a column which tracking the version history of an "append only" memo column.

Note, the strongly typed update/delete methods are not supported for version history columns (the data is supposed to be immutable). That said, the "raw" update/delete methods are supported for those that really want to muck with the version history data.
