Event Routing

The goal of this library is to provide a generic one-way event routing mechanism for any kind of events.

Principles

The main component of this library is the Hub<T> class which implements IHub<T> and handles routing of events via configured routers.

The type of routed events is specified as the generic type parameter T to the class Hub<T> and must implement IRoutable.

The routers forwarding events of type IRoutable themselves must implement IRouter<T> with T being the type of events.

Routers can be assigned to a hub by calling a hub's ReconfigureAsync method handing in an instance of HubConfiguration<T> which contains references to the router instances.

A configuration can also specify preprocessors implementing IRoutablePreprocessor<T>. Preprocessors are automatically invoked for each single forwarded event by the hub right before handing the event over to the configured routers allowing for filtering or replacing of events depending on the preprocessors' logic. Any preprocessor may decide via the OnEnqueueing property whether the preprocessing needs to be done immediately while enqueueing (in a blocking fashion) or asynchronously right before forwarding an event to the configured routers.

A built-in preprocessor is FilterPreprocessor which allows for simple filtering based on allowing and blocking conditions. In order to have an event pass the filter, all allowing conditions must be successfully tested while none of the blocking conditions may apply.

Instead of creating a HubConfiguration<T> instance directly, the builder HubConfigurationBuilder<T> can also be used to fluently define a hub configuration and finally calling the Build() method to create a related HubConfiguration<T> instance.

Example

The example app EventRouter.SampleApp defines an event MessageEvent containing a printable Message, a router ConsoleRouter which prints forwarded events on the console, and utilizes a Hub configured to forward all events whose messages start with the text Important.

Known Issues

  • After calling ReconfigureAsync(null, ?) the previously configured queue capacity is still in order.
