const mixinafBedSheet::HttpStatusProcessor

Implement to define a HttpStatusProcessor.

HttpStatusProcessors process HttpStatus objects returned from request handler methods, and are mapped to specific status codes.

When a HttpStatus object is returned from a request handler method, the HttpStatusProcessor with the matching status code is used to handle it.

If no matching processor can be found, a default processor is used. You can override the default processor by setting it in ApplicationDefaults:

@Contribute { serviceType=ApplicationDefaults# } 
static Void configureApplicationDefaults(MappedConfig config) {
  config[BedSheetConfigIds.defaultHttpStatusProcessor] = config.autobuild(MyStatusPage#)
}

IOC Configuration

Instances of HttpStatusProcessor should be contributed to the HttpStatusProcessors service and mapped to an Int representing the status code it handles.

For example, in your AppModule class:

@Contribute { serviceType=HttpStatusProcessors# }
static Void contributeHttpStatusProcessors(MappedConfig config) {
    config[404] = My404PageHandler()
}
