## Install

```bash
$ yarn add @comunica/bus-function-factory
```

## Usage

## Bus usage

* **Context**: `"https://linkedsoftwaredependencies.org/bundles/npm/@comunica/bus-function-factory/^1.0.0/components/context.jsonld"`
* **Bus name**: `ActorFunctionFactory:_default_bus`

When a mediator is required, the argument should get the `MediatorFunctionFactoryUnsafe` and manually cast it to `MediatorFunctionFactory`.
We require this work around because Components.js does not support the complex type of MediatorFunctions.

## Creating actors on this bus

Actors extending [`ActorFunctionFactory`](TODO:jsdoc_url) are automatically subscribed to this bus.
