Compatibility of Threading Models

This table shows which threading models can you use as children based on the model of the parent.

Private

When you assign an object with a threading model to another object with a threading model as a child, the assignment statement will block until the thread has full access to both objects. For a Synchronized object, that means it has the lock. For a ReaderWriterSynchronized object, that means it has the write lock. The same is true for an assignment which removes the parent-child link from two objects.
