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.
