Method Detail

getNodeKey

public abstract Key getNodeKey(SendableRequestItem token)

Get a numbered key to fetch.

preRegister

public abstract boolean preRegister(ClientContext context,
                                    boolean toNetwork)

Called after checking the datastore and before registering the request to be sent. Some gets may want to cancel here, some may want to send an event to FCP.

Parameters:

toNetwork - If true, we are actually going to send requests (unless we cancel in this callback). If false, we completed all the work assigned.

Returns:

True to cancel the request at this stage i.e. not go to network, in which case *the BSG must handle the failure itself*.
