/**
|
||||
* Helper class to perform an operation asynchronous but keeping the order in respect to a given key.
|
||||
* <p>
|
||||
* A typical use pattern for this helper class consists of callbacks for an abstract entity where the order of callbacks
|
||||
* matters, which eventually call user code in form of listeners. Since the order the callbacks matters, you need to use
|
||||
* synchronous connection listeners. But if those listeners would invoke the user provided listeners, and if those user
|
||||
* provided listeners would take a long time to complete, or even worse, block, then Smack's total progress is stalled,
|
||||
* since synchronous connection listeners are invoked from the main event loop.
|
||||
* </p>
|
||||
* <p>
|
||||
* It is common for those situations that the order of callbacks is not globally important, but only important in
|
||||
* respect to an particular entity. Take chat state notifications (CSN) for example: Assume there are two contacts which
|
||||
* send you CSNs. If a contact sends you first 'active' and then 'inactive, it is crucial that first the listener is
|
||||
* called with 'active' and afterwards with 'inactive'. But if there is another contact is sending 'composing' followed
|
||||
* by 'paused', then it is also important that the listeners are invoked in the correct order, but the order in which
|
||||
* the listeners for those two contacts are invoked does not matter.
|
||||
* </p>
|
||||
* <p>
|
||||
* Using this helper class, one would call {@link #performAsyncButOrdered(Object, Runnable)} which the remote contacts
|
||||
* JID as first argument and a {@link Runnable} invoking the user listeners as second. This class guarantees that
|
||||
* runnables of subsequent invocations are always executed after the runnables of previous invocations using the same
|
||||
* key.
