Interceptor Events

Last updated 7 years ago

Was this helpful?

The module configuration object is also treated as an Interceptor once it is created and configured.

Life-cycle Events

There are two life-cycle callback events you can declare in your ModuleConfig.cfc:

  • onLoad() : Called when the module is loaded and activated

  • onUnLoad() : Called when the module is unloaded from memory

This gives you great hooks for you to do bootup and shutdown commands for this specific module. You can build a or like application very easily all built in to the developing platform.

function onLoad(){
  // Register some tables in my database and activate some features
  controller.getWireBox().getInstance('MyModuleService').activate();
    log.info( 'Module #this.title# loaded correctly' );
}

function onUnLoad(){
  // Cleanup some stuff and logit
  controller.getWireBox().getInstance('MyModuleService').shutdown();

  // Log we unloaded
  log.info( 'My module unloaded successfully!' );
}

Custom Events

Also, remember that the configuration object itself is an interceptor so you can declare all of the framework's interception points in the configuration object and they will be registered as interceptors.

function preProcess(event, interceptData){
  // I just intercepted ALL incoming requests to the application
  log.info('The event executed is #arguments.event.getCurrentEvent()#');
}

This is a powerful feature, you can create an entire module based on a single CFC and just treat it as an interceptor. So get your brain into gear and let the gas run, you are going for a ride baby!
