Moving Through the Version Graph

Repository helps you move through the version graph in the following ways:

• Every object version has a collection of successor versions – the other versions of the same object that immediately follow in the version graph. In the following figure, Version 5 has two successor versions, Version 9 and Version 7. An object version's set of successor versions can be null. For example, Version 11 has no successors.

• Every object version has a collection of predecessor versions – the other versions of the same object that immediately precede it in the version graph. In the preceding figure, for example, Version 11 has three predecessor versions: Version 9, Version 7, and Version 10.
  
  
• Every object version (except Version 1) has a predecessor creation version – the predecessor version from which the current object version was created. For example, of Version 11's three predecessor versions, only Version 9 is its predecessor creation version.
  
  
• Every object version has a collection of object versions – the entire set of versions of the object.
