Versioning a KM Document

The example below shows how to implement custom code in your application so that you can create different versions of a KM Document.

1. Create a new application:

   More information: Creating Composite Application Development Components .

2. Create an application service in your application:

   More information: Creating Application Services .

3. Set dependency to DocContent, Document, and RelatedObject:

   More information: Defining Application Service Dependencies .

4. To enable document versioning, import the following code in the implementation of the operation:

   DocContentServiceLocal docContentLocal = getDocContentServiceLocal();
   
   Collection<String> rids = docContentLocal.getRelatedObjectRids(docKey);
   
   
   
   String rid = rids.iterator().next();
   if ( !docContentLocal.isDocumentVersioned(rid)) 
   
   docContentLocal.enableDocumentVersioning(rid);
   

5. To check out the document for editing, import the following code in the implementation of the application service:

   docContentLocal.checkout(rid);
   
   

6. To check in the new version of the document, import the following code:

    byte[] contentVer2 = getResFileContentVersion2();
   
        docContentLocal.checkin(rid, contentVer2);
   

7. To get the whole version history of the document, import the following code:

   String [] versionHistoryRidsArrStr = (String []) 
   docContentLocal.getVersionHistory(rid).toArray(new String[0]);
   
   

8. To set a version of a document as current version:

   docContentLocal.setAsCurrentVersion
   
       (versionHistoryRidsArrStr[versionHistoryRidsArrStr.length -1],
   
        rid);
