The Application Data Modeler allows robust modeling of state and messages in XML. ADM generates Plain Old Java Objects that can be used by applications with ease while supporting highly optimized serialization under the covers. |
Atomic Event Processing refers to the transactional event processing paradigm in Talon application that is implemented by an AepEngine. In Atomic Event Processing processing of inbound messages, business logic processing, replication and persistence of state changes and outbound messaging is orchestrated in an atomic and (crucially) pipelined fashion. This relieves application event (message) handlers from the burden of coding for message loss and duplication and allows. |
The AepEngine sits at the core of every talon application. It drives the transactional machinery that coordinates messaging (SMA), state (ODS) and event dispatch (application handlers). |
An event emitted by an AepEngine when a message is received, but not handled by an any EventHandler. An application can provide an EventHandler for this event type to quarantine or or take other actions prior to the message being acknowledged. |
