Method Detail

id
public java.lang.String id()
Description copied from interface:XMPPImplIfc
Methodid
returns a unique ID of the plugin. Each plugin has own, unique ID which is used in the configuration file to determine whether it needs to be loaded or not. In most cases the ID can be equal to XMLNS of the packages processed by the plugin.- Specified by:
id
in interfaceXMPPImplIfc
- Returns:
- a
String
value
-
getMsgCarbonPaths
public java.lang.String[] getMsgCarbonPaths()
-
setMsgCarbonPaths
public void setMsgCarbonPaths(java.lang.String[] matcherStrs)
-
process
public void process(Packet packet, XMPPResourceConnection session, NonAuthUserRepository repo, java.util.Queue<Packet> results, java.util.Map<java.lang.String,java.lang.Object> settings) throws XMPPException
- Specified by:
process
in interfaceXMPPProcessorIfc
- Parameters:
packet
- packet is which being processed. This parameter may never be null. Even though this is not immutable object it mustn't be altered. None of it's fields or attributes can be changed during processing.session
- user session which keeps all the user session data and also gives an access to the user's repository data. It allows for storing information in a permanent storage or in memory only during the live of the online session. This parameter can be null if there is no online user session at the time of the packet processing.repo
- this is a user data storage which is normally used when the user session (parameter above) is null. This is repository allows for a very restricted access only. It allows for storing some user private data (doesn't allow overwriting existing data) like messages for offline users and it also allows for reading user public data like VCard.results
- this a collection with packets which have been generated as input packet processing results. Regardless a response to a user request is sent or the packet is forwarded to it's destination it is always required that a copy of the input packet is created and stored in the results queue.settings
- this map keeps plugin specific settings loaded from the Tigase server configuration. In most cases it is unused, however if the plugin needs to access an external database that this is a way to pass database connection string to the plugin.- Throws:
XMPPException
-
prepareSkipForkingToList
protected java.util.Set<JID> prepareSkipForkingToList(Packet packet, XMPPResourceConnection session, java.util.Map<JID,java.lang.Boolean> resources) throws NotAuthorizedException
- Throws:
NotAuthorizedException
-
supDiscoFeatures
public Element[] supDiscoFeatures(XMPPResourceConnection session)
Description copied from interface:XMPPImplIfc
MethodsupDiscoFeatures
returns an array of XMLElement
s with service discovery features which have to be returned to the client uppon request. Service discovery features returned by this method correspond to services supported by this plugin.- Specified by:
supDiscoFeatures
in interfaceXMPPImplIfc
- Overrides:
supDiscoFeatures
in classXMPPProcessor
- Parameters:
session
- aXMPPResourceConnection
value- Returns:
- an
Element[]
value
-
supElementNamePaths
public java.lang.String[][] supElementNamePaths()
Description copied from interface:XMPPImplIfc
MethodsupElementNamePaths
returns an array of element names in form of a full path to the XML element for stanzas which can be processed by this plugin. Each element name path corresponds to XMLNS returned in array bysupNamespaces()
method. The element path itself is represented by a String array with each path element as a separate String.- Specified by:
supElementNamePaths
in interfaceXMPPImplIfc
- Overrides:
supElementNamePaths
in classXMPPProcessor
- Returns:
- a
String[][]
value is an array for element paths for which the plugin offers processing capabilities. Each path is in form of a String array in order to reduce parsing overhead.
-
supNamespaces
public java.lang.String[] supNamespaces()
Description copied from interface:XMPPImplIfc
MethodsupNamespaces
returns an array of name-spaces for stanzas which can be processed by this plugin. Each namespace corresponds to element name returned in array bysupElemenets()
method.- Specified by:
supNamespaces
in interfaceXMPPImplIfc
- Overrides:
supNamespaces
in classXMPPProcessor
- Returns:
- a
String[]
value
-
filter
public void filter(Packet packet, XMPPResourceConnection session, NonAuthUserRepository repo, java.util.Queue<Packet> results)
- Specified by:
filter
in interfaceXMPPPacketFilterIfc
-
stateChanged
@HandleEvent protected void stateChanged(MessageCarbons.MessageCarbonsStateChangedEvent event)
Method responsible for handingMessageCarbonsStateChangedEvent
and marking JIDs of user as MessageCarbons enabled/disabled.
-
presenceUpdate
@HandleEvent protected void presenceUpdate(UserPresenceChangedEvent presenceEvent) throws NotAuthorizedException
Method handlesUserPresenceChangedEvent
and synchronizes state of JIDs for MessageCarbons for particular user.- Throws:
