Class ReconnectionManager

java.lang.Object

org.jivesoftware.smack.ReconnectionManager

public final class ReconnectionManager
extends Object

Handles the automatic reconnection process. Every time a connection is dropped without the application explicitly closing it, the manager automatically tries to reconnect to the server.

There are two possible reconnection policies: ReconnectionManager.ReconnectionPolicy.RANDOM_INCREASING_DELAY - The reconnection mechanism will try to reconnect periodically:

1. For the first minute it will attempt to connect once every ten seconds.
2. For the next five minutes it will attempt to connect once a minute.
3. If that fails it will indefinitely try to connect once every five minutes.

ReconnectionManager.ReconnectionPolicy.FIXED_DELAY - The reconnection mechanism will try to reconnect after a fixed delay independently from the number of reconnection attempts already performed.

Interrupting the reconnection thread will abort the reconnection mechanism.

Method Detail

getInstanceFor

public static ReconnectionManager getInstanceFor(AbstractXMPPConnection connection)

Get a instance of ReconnectionManager for the given connection.

Parameters:

connection -

Returns:

a ReconnectionManager for the connection.

setEnabledPerDefault

public static void setEnabledPerDefault(boolean enabled)

Set if the automatic reconnection mechanism will be enabled per default for new XMPP connections. The default is 'false'.

Parameters:

enabled -

getEnabledPerDefault

public static boolean getEnabledPerDefault()

Get the current default reconnection mechanism setting for new XMPP connections.

Returns:

true if new connection will come with an enabled reconnection mechanism

setDefaultFixedDelay

public static void setDefaultFixedDelay(int fixedDelay)

Set the default fixed delay in seconds between the reconnection attempts. Also set the default connection policy to ReconnectionManager.ReconnectionPolicy.FIXED_DELAY

Parameters:

fixedDelay - Delay expressed in seconds

setDefaultReconnectionPolicy

public static void setDefaultReconnectionPolicy(ReconnectionManager.ReconnectionPolicy reconnectionPolicy)

Set the default Reconnection Policy to use.

Parameters:

reconnectionPolicy -

addReconnectionListener

public boolean addReconnectionListener(ReconnectionListener listener)

Add a new reconnection listener.

Parameters:

listener - the listener to add

Returns:

true if the listener was not already added

Since:

4.2.2

removeReconnectionListener

public boolean removeReconnectionListener(ReconnectionListener listener)

Remove a reconnection listener.

Parameters:

listener - the listener to remove

Returns:

true if the listener was active and got removed.

Since:

4.2.2

setFixedDelay

public void setFixedDelay(int fixedDelay)

Set the fixed delay in seconds between the reconnection attempts Also set the connection policy to ReconnectionManager.ReconnectionPolicy.FIXED_DELAY.

Parameters:

fixedDelay - Delay expressed in seconds

setReconnectionPolicy

public void setReconnectionPolicy(ReconnectionManager.ReconnectionPolicy reconnectionPolicy)

Set the Reconnection Policy to use.

Parameters:

reconnectionPolicy -

enableAutomaticReconnection

public void enableAutomaticReconnection()

Enable the automatic reconnection mechanism. Does nothing if already enabled.

disableAutomaticReconnection

public void disableAutomaticReconnection()

Disable the automatic reconnection mechanism. Does nothing if already disabled.

isAutomaticReconnectEnabled

public boolean isAutomaticReconnectEnabled()

Returns if the automatic reconnection mechanism is enabled. You can disable the reconnection mechanism with disableAutomaticReconnection() and enable the mechanism with enableAutomaticReconnection().

Returns:

true, if the reconnection mechanism is enabled.
