Constructor Detail

SequenceProxyPushSupplierImpl

public SequenceProxyPushSupplierImpl(AbstractAdmin myAdminServant,
                                     ChannelContext channelContext)

this callback is called by the TimerDaemon. Check if there are pending Events and deliver them to the Consumer. As there's only one TimerDaemon its important to block the daemon only a minimal amount of time. Therefor the Callback does not do the actual delivery. Instead a DeliverTask is scheduled for this Supplier.
