lockScope can be one of the following: 1 - Shared Lock 2 - Exclusive Lock timeout should be an integer value, that indicates the timeout in milliseconds
*/ int lockType = 1; int lockScope = 2; int timeout = 100000; String token = docContentLocal.lockDocument( rid,lockType,lockScope,timeout); |
5. To release a newly obtained lock or all locks, import the following code:
docContentLocal.unlockDocumentWithToken(rid, token); docContentLocal.unLockDocument(rid);
