public interface Redirector
```
Strategy interface for helping a Ring instance decide whether to redirect SessionPrx creation to another SessionManagerI instance. The Ring instance is passed in

Since:

Beta-4.0-RC2

`static interface`	`Redirector.Context`	Interface implemented by Ring instances to allow passing in the context necessary for making strategy decisions.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`chooseNextRedirect(Redirector.Context context, java.util.Set<java.lang.String> nodeUuids)`	Gives the `Redirector` a chance to configure the next appropriate redirect based on the `Set` of current `Node` uuids.
`Glacier2.SessionPrx`	`getProxyOrNull(Redirector.Context context, java.lang.String userId, Glacier2.SessionControlPrx control, Ice.Current current)`	Create or retrieve and returns a `SessionPrx` which the current method takes control of.
`void`	`handleRingShutdown(Redirector.Context context, java.lang.String uuid)`	Gives the `Redirector` a chance to remove the current `Ring` when it is being shutdown.

Method Detail

getProxyOrNull

Glacier2.SessionPrx getProxyOrNull(Redirector.Context context,
                                   java.lang.String userId,
                                   Glacier2.SessionControlPrx control,
                                   Ice.Current current)
                            throws Glacier2.CannotCreateSessionException

Create or retrieve and returns a SessionPrx which the current method takes control of. If it is not returned, then it should be properly destroyed.

Parameters:: userId - Not null.; control -; current -
Returns:: Possibly null.
Throws:: Glacier2.CannotCreateSessionException

chooseNextRedirect

void chooseNextRedirect(Redirector.Context context,
                        java.util.Set<java.lang.String> nodeUuids)

Gives the Redirector a chance to configure the next appropriate redirect based on the Set of current Node uuids.

handleRingShutdown

void handleRingShutdown(Redirector.Context context,
                        java.lang.String uuid)
