The loopback backend

This backend allows the user to create logical mapping channels, for example to exchange triggering channels easier later. All events that are input are immediately output again on the same channel.

Global configuration

All global configuration is ignored.

Instance configuration

All instance configuration is ignored

Channel specification

A channel may have any string for a name.

Example mapping:

loop.foo < loop.bar123

Known bugs / problems

It is possible (and very easy) to configure loops using this backend. Triggering a loop will create a deadlock, preventing any other backends from generating events. Be careful with bidirectional channel mappings, as any input will be immediately output to the same channel again.
