Examples

A set of examples that explore the usage of Fluxtion in a variety of scenarios. All examples are on github as a single project, cloning the repo will help the reader explore the code locally and improve the learning experience.

Executing and event processor

All projects that build a Fluxtion EventProcessor at runtime follow similar steps

  1. Mark event handling methods with annotations or via functional programming
    • Create a maven or gradle project adding the Fluxtion compiler dependency to the project runtime classpath
    • Write pojo’s that will provide event driven logic, set references between the pojo’s as per normal java
    • Annotate a method to indicate it is an event handling entry pont or a callback trigger method
    • Export a service, any exported methods are entry points to the event processor
  2. Build the event processor using fluxtion compiler utility
    • Calling one of the Fluxtion compile/interpret methods passing in the list of nodes to the builder method.
    • An EventProcessor instance is returned ready to be used
  3. Integrate the event processor in the app and feed it events
    • Call EventProcessor.init() to ensure the graph is ready to process events
    • To publish events to the processor call EventProcessor.onEvent(object)
    • To call exported service functions on the event processor
      • Lookup the exported service with EventProcessor.getExportedService()
      • Store the service reference and call methods on it
