LinkValueStamp is an abstract type that denotes information about the last update to a link value of an object. It is a tuple that consists of all the fields in AttributeStamp, plus the following additional fields:
timeCreated: The date and time at which the first originating update was made.
timeDeleted: The date and time at which the last replicated update was made that deleted the value, or 0 if the value is not currently deleted.
Values of LinkValueStamp are partially ordered. Let d be the result of x.dwVersion - y.dwVersion, cast as a 32-bit integer. Then given two stampsx and y, x is said to be greater than y if any of the following is true:
x is not null and y is null
x.timeCreated > y.timeCreated
x.timeCreated = y.timeCreated and d > 0
x.timeCreated = y.timeCreated and d = 0 and x.timeChanged > y.timeChanged
x.timeCreated = y.timeCreated and d = 0 and x.timeChanged = y.timeChanged and x.uuidOriginating > y.uuidOriginating
A value x of type LinkValueStamp may be converted to and from its wire format y of type PROPERTY_META_DATA_EXT by associating the values of fields in x with the values of the like-named fields in y and y.MetaData.
Note The value of timeDeleted does not appear in the wire format. On the wire, the PROPERTY_META_DATA_EXT value always appears as a value of the MetaData field of a REPLVALINF structure. Given value x of type LinkValueStamp and value z of type REPLVALINF, z.fIsPresent is TRUE if x.timeDeleted is 0 and FALSE if x.timeDeleted is nonzero.
