Lightweight handle representing a signaler‐to‐slot connection.

== Synopsis

Declared in `<bdlmt_signaler.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
class SignalerConnection;

== Description

This `class` represents a connection between a signaler and a slot. It is a lightweight object that has the ability to query whether the signaler and slot are currently connected, and to disconnect the slot from the signaler. Note that, unless otherwise specified, it is safe to invoke any method of `SignalerConnection` from the context of its associated slot, or any other slot.
