Process or deliver a batch of messages heading towards the host.
Messages should be processed and passed to the next connectivity plug-in in the chain, which is typically provided by the Transport's or Codec's hostSide pointer.
The ability to handle messages in batches is provided to allow amortising the costs of delivering events. The batch is defined as all Messages from start up to but excluding end. The callee may modify the messages, typically by moving their contents elsewhere.
Threading: Plug-ins are required to ensure that they do not call into the next plug-in in their chain from more than one thread concurrently (although it does not have to be the same thread each time). Plug-ins may therefore assume that no additional locking is required in this method to protect access to the plug-in's state. The plug-in should be as responsive as possible to the Plugin.shutdown() method, which may be called at any time on any thread. If this method throws then the exception will be logged and the batch of messages dropped.
Implements com::softwareag::connectivity::HostSide.
