/**
* Runtime hooks engine
*
* The following hooks can be used:
*
* Message sending
* - `onSend` - passed an array of `SendEvent` objects. The messages inside these objects are exactly what the node has passed to `node.send` - meaning there could be duplicate references to the same message object.
* - `preRoute` - passed a `SendEvent`
* - `preDeliver` - passed a `SendEvent`. The local router has identified the node it is going to send to. At this point, the message has been cloned if needed.
* - `postDeliver` - passed a `SendEvent`. The message has been dispatched to be delivered asynchronously (unless the sync delivery flag is set, in which case it would be continue as synchronous delivery)
* - `onReceive` - passed a `ReceiveEvent` when a node is about to receive a message
* - `postReceive` - passed a `ReceiveEvent` when the message has been given to the node's `input` handler(s)
* - `onComplete` - passed a `CompleteEvent` when the node has completed with a message or logged an error
*
* @mixin @node-red/runtime_hooks
