nodeConnected
This is a handler method which is called when a new node connects to the cluster.- Parameters:
node
- is a cluster node id.
-
nodeDisconnected
This is a handler method which is called when a node disconnects from the cluster.- Parameters:
node
- is a cluster node id.
-
processPacket
-
getNodesConnected
The method returns all cluster nodes currently connected to the cluster node.- Returns:
- List of all cluster nodes currently connected to the cluster node.
-
getConnectionRecord
Returns a ConnectionRecord object associated with this user's full JID if it exists in the cache or null if it does not. All parts of the user's JID are checked and ConnectionRecord is returned only if there is a match for all parts.- Parameters:
jid
- is an instance of the user's full JID.- Returns:
- ConnectionRecord instance associated with given user's JID or null if there is no ConnectionRecord in the cache.
-
getConnectionRecordInstance
E getConnectionRecordInstance() -
getConnectionRecords
Returns a set with all ConnectionRecords found in the cache for a given user ID, that is BareJID. In other words all user's resources/connectionIDs found in the cache associated with user's account.- Parameters:
bareJID
- is an instance of the user's BareJID, that is account ID.- Returns:
- a Set instance with all ConnectionRecords found for a given BareJID. Note, the result may be null or it maybe an empty Set or non-empty set.

getDefaults
Deprecated.This method is used for configuration purpose. Following the convention used in the Tigase project this method is supposed to provide configuration defaults. All parameters which exist in configuration file overwrite corresponding default parameters. If some parameters are missing in configuration file defaults are used then.
A compiled set of parameters is then passed tosetProperties
method.- Parameters:
params
- aMap
with properties loaded from init.properties file which should be used for generating defaults.- Returns:
- a
Map
with all the class default configuration parameters.
-
getStatistics
Add the strategy statistics to the List. -
setClusterController
-
setProperties
Method used to pass configuration parameters to the class. Parameters are stored inMap
which contains compiles set of defaults overwritten by parameters loaded from configuration file.
If he implementation took a good care of providing defaults for all parameters no parameter should be missing.- Parameters:
props
- aMap
with all configuration parameters for the class.
