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. SMACK-265

/**
|
|
* Defines a way to filter packets for particular attributes. Packet filters are used when
|
|
* constructing packet listeners or collectors -- the filter defines what packets match the criteria
|
|
* of the collector or listener for further packet processing.
|
|
* <p>
|
|
* Several simple filters are pre-defined. These filters can be logically combined for more complex
|
|
* packet filtering by using the {@link org.jivesoftware.smack.filter.AndFilter AndFilter} and
|
|
* {@link org.jivesoftware.smack.filter.OrFilter OrFilter} filters. It's also possible to define
|
|
* your own filters by implementing this interface. The code example below creates a trivial filter
|
|
* for packets with a specific ID (real code should use {@link PacketIDFilter} instead).
|
|
*
|
|
* <pre>
|
|
* // Use an anonymous inner class to define a packet filter that returns
|
|
* // all packets that have a packet ID of "RS145".

|
* PacketFilter myFilter = new PacketFilter() {
|
|
* public boolean accept(Packet packet) {
|
|
* return "RS145".equals(packet.getPacketID());
|

* }

* PacketCollector myCollector = packetReader.createPacketCollector(myFilter);
