Aspose::Words::RevisionGroupCollection::GetEnumerator method

RevisionGroupCollection::GetEnumerator method

Returns an enumerator object.

System::SharedPtr<System::Collections::Generic::IEnumerator<System::SharedPtr<Aspose::Words::RevisionGroup>>> Aspose::Words::RevisionGroupCollection::GetEnumerator() override

Examples

Shows how to work with a document’s collection of revisions.

// This collection itself has a collection of revision groups.
// Each group is a sequence of adjacent revisions.
std::cout << revisions->get_Groups()->get_Count() << " revision groups:" << std::endl;

// Iterate over the collection of groups and print the text that the revision concerns.
{
    SharedPtr<System::Collections::Generic::IEnumerator<SharedPtr<RevisionGroup>>> e = revisions->get_Groups()->GetEnumerator();
    while (e->MoveNext())

                  << std::endl;
    }
}

// Each Run that a revision affects gets a corresponding Revision object.
// The revisions' collection is considerably larger than the condensed form we printed above,

        // property will always be in use, while the ParentNode will always be null.
