ce203e76b5 Use AbstractNodeInformationProvider where possible 2014-10-13 22:35:45 +02:00
Florian Schmaus
b54d133b36 Add MultiUserChatManager
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.

c674808a4a Improve MultiUserChat
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.

365c71db79 Rework MultiUserChat
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.

98a3c46e9a Add XMPPConnection.createPacketcollectorAndSend(PacketFilter, Packet)
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.

8ce474b0df Improve MUC Presence interceptors
Use PresenceListener as intercepting callback interface.

facilities of the XMPPConnection.

Florian Schmaus
63d52f6eaa Replace PacketInterceptor with PacketListener
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.

e835df5641 Improve MUC message and presence listeners
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.

Florian Schmaus
6980c8e63d Rework Smack Provider design
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.

fc39ac88bd Add support for retrieving PubSub Node affiliations
This also marks the starting point for extending the PubSub API to allow
additional packet extensions to be added to the request. This is for
example useful if one wants to limit the result with "Result Set

Fixes SMACK-580.

Also add Matcher for CharSequences.
