Versioning a KM Document 

Use

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

Procedure

...

       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);
