Make sure that the Packets are of type Message. To prevent:

apply the Manager pattern to 'muc'. This prevents the user creating
multiple MultiUserChat instances for the same MUC.
Move the static method from MultiUserChat to MultiUserChatManager.
Also add AbstractNodeInformationProvider.
Use CopyOnWriteArraySet for listeners, remove the old reflection based
listener invocation approach.
Remove unnecessary casts.
Return List instead of Collection where possible.
sendMessage(Message) now set's the MUC as 'to' and the message type to
groupchat.
remove PacketMultiplexListener, RoomListenerMultiplexor and
ConnectionDetachedPacketCollector(Test), which was a bunch of
(in same cases redundant) code that formed a complex construct that
presumably tried to make MultiUserChat instances easily garbage
collect-able.
Now, MultiUserChat should be eligible for gc if the userHashLeft() is
invoked before the reference to the instance is dropped, which should be
the case in the most scenarios. Otherwise the connection may references
the MultiUserChat instance over Packet(Listener|Interceptor)s preventing
the gc.
Using
createPacketCollector(filter);
sendPacket(packet);
was error prone, i.e. the PacketCollector could leak if sendPacket()
would throw an exception and the user forgot to call
PacketCollector.cancel(). For cases where
createPacketCollectorAndSend(IQ) is not sufficient (because we don't
send IQs), createPacketCollectorAndSend(PacketFilter, Packet) is now
used, which does take care that the PacketCollector does not leak if
sendPacket() throws an Exception.
Use PresenceListener as intercepting callback interface.
Remove the for-each loops in MultiUserChat by using the interception
facilities of the XMPPConnection.
Add ToFilter.
both serve the same purpose: As callback for Packets. There is no need
to have both, so remace PacketInterceptor and let PacketListener take
its place. Some classes like ChatStateManager can now use
MessageListener as interceptor callback, which is more convenient.
instead of using a PacketListener, which means that the user has to
downcast the Packet to Message, we now use a Listener which callback
parameter is already Message/Presence.
It is necessary to introduce MessageListener and PresenceListener, which
are interfaces that have a callback for Message/Presence instead of
Packet. The 'old' MessageListener is renamed to ChatMessageListener.
Use Generics in ConnectionDetachedPacketCollector.
this is the first stop towards fixing "SMACK-65: parsing should look for
depth", by providing the initial parsing depth to the provider. Some
methods (.e.g parseMessage) now use the depth as abort condition,
instead of a unclean String equals check.
parseIQ() and parseExtension() where both renamed to parse.
This also restricts the Exceptions thrown by the parse method, to just
XmlPullParserException, IOException and SmackException (not really a big
victory, but nevertheless a slight improvement).
StreamFeatureProvider is now gone, we simply use PacketExtensionProvider
for stream features.
- De-duplicate code by moving it into AbstractXMPPConnection
- Introduce TopLevelStreamElement as superclass for all XMPP stream elements.
- Add SynchronizationPoint, ParserUtils
- Add ParserUtils
Fixes SMACK-333 and SMACK-521
It's a common pattern to look for all services hosted under the users
service that provide a given feature. Let's provide an API for that and
use that API in the methods that benefit from it.
Removes a ton of duplicate code, mostly related to MUCItem being
duplicated in MUCOwner and MUCAdmin, but also some other duplicate code.
Make MUC code use XmlStringBuilder.
Add ELEMENT and NAMESPACE constants to the appropriate places. Also add
"static <MUCPacketExtension> getFrom(Packet)" methods.
Make some MUC classes implement Element.
instead of using the old baseName=smack appendix=project.name approach,
we are now going convention over configuration and renaming the
subprojects directories to the proper name.
Having a prefix is actually very helpful, because the resulting
libraries will be named like the subproject. And a core-4.0.0-rc1.jar is
not as explicit about what it actually *is* as a
smack-core-4.0.0-rc1.jar.
