In IBM® Rational® ClearQuest® an entity may have history information associated with it. Each record has a history field, and this field can have multiple history entries. Each history entry is a line of text describing the modification. All history objects are read-only, because the history entries for a data record are created automatically by IBM Rational ClearQuest.
A History object contains a string that describes the modifications to the record.
The History object encapsulates the String that is displayed for one entry in a history field of a data record. The History object has only one Visual Basic property (Value) and one Perl method (GetValue).
