| SettingManager | | public class SettingManager (Code) | | Allows hierarchical management of application settings. The settings API
has been designed with the following goals:
- speed: all the settings tree is kept into memory
- transactional: changes follow the rules of transactions. The only issue
is that changes are not visible until commit. If a thread
changes a value and then reads it, the thread gets the old
value. Added settings will not be visible and removed ones
will still be visible until commit.
- concurrent: many thread can access the settings API at the same time. A
read/write lock is used to arbitrate threads
Multiple removes: there are no issues. If thread A removes a subtree S1 and
another thread B removes a subtree S2 inside S1, the first thread to commit
succeeds while the second always rises a 'cannot serializable exception'.
In any commit combination, the settings integrity is maintained.
