===== EmptyMessage =====

[[EmptyMessage]] is a built-in [[BaseMessage]] used when a [[Topic]] or [[AsyncTopic]] is intended purely as a signal and no payload data needs to be transmitted.

For these cases, the static ''Default'' instance should generally be used instead of creating a new EmptyMessage for every broadcast. This avoids unnecessary allocations for a message that carries no state.

=== Fields ===
^Field | static readonly [[EmptyMessage]] **Default** |
^Description | Shared instance of [[EmptyMessage]] intended for broadcasts that do not require a payload. Using this instance avoids allocating a new EmptyMessage for each broadcast. |
