Is it possible to check if a database lock is placed on object?

If some thread placed a database lock on the object with IDfPersistentObject.lock(), is it possible to quickly determine from the other thread that the object was locked?

If you call IDfPersistentObject.lock() or save() from the other thread, the thread will be blocked until the first one deals with transaction. It is not good for my application because such "unconditional blocking" (1) unpredictably consumes time and (2) consumes content server memory. Is there some kind of isLocked() method which quickly returns a result?

Try checking the value of lock owner: IDfSysobject.getLockOwner()

getLockOwner checks who checked out a document. I don't think it's related to this lock() method. In fact, I've never used it myself and I a little puzzled by it. How are you supposed to release such a lock? There is no method to unlock it. Also the Javadoc doesn't have a lot of details. And I'm not aware that Content Server exposes a locking mechanisms to objects which are not sysobjects.

"How are you supposed to release such lock?"

This knowledge was "deprecated" with the "Content Server API Reference Manual", which contained the usage notes of "Lock" API server method. It will be great if your colleagues put the notes into javadocs…
