# class Log::BroadcastBackend

- Log::BroadcastBackend
- Log::Backend
- Reference
- Object

##
Overview

A backend that broadcast to others backends. Each of the referenced backends may have a different severity level filter.

When this backend level is set that level setting takes precedence over the severity filter of each referenced backend.

This backend is not to be used explicitly. It is used by `Log::Builder` configuration to allow a given source to emit to multiple backends.
