| /* |
| * Synchronization Notes |
| * |
| * 1. There is an internal lock object that's used to synchronize access to |
| * the data structure. By synchronizing on an internal object, outside code |
| * cannot cause a deadlock by synchronizing on the FacetedProject object. |
| * |
| * 2. Readers synchronize on the lock object for the duration of the method |
| * call. This protects the readers from writers and makes sure that reader |
| * is not reading stale data from thread's local memory. |
| * |
| * 3. All collections that are returned by the reader methods are guaranteed |
| * to not change after the fact. This is implemented through a copy-on-write |
| * policy. |
| * |
| * 4. Writers synchronize on the lock object briefly at the start of the method |
| * and mark the FacetedProject as being modified. If the project is already |
| * being modified, the new writer will wait. Inside the bodies of the |
| * modifier methods, the writer thread is only synchronized on the lock |
| * object while modifying the internal datastructures. These synchronization |
| * sections are kept short and they never span over code that might modify |
| * file system resources. This is done to prevent deadlocks. Once the write |
| * is complete, the writer thread synchronizes on the lock object, resets the |
| * "being modified" flag, and notifies any writers that may be waiting. |
