class

PlaceOS::Model::GroupSignageTemplate::ChangeFeed(T)

Inherits Iterator < Enumerable < Reference < Object

Junction between Group and SignageTemplate (both authority-scoped, UUID). Same M:N shape as GroupPlaylistItem — allows templates to be shared with groups so they can manage their own templates.

Presence-only — no per-row permission bitmask, no GroupHistory audit. A user's capability on a linked template comes from their GroupUser.permissions within the group.

Both sides must share an authority — enforced here at the model layer (no single FK can express it).

Constructors

new(id : Tuple(UUID, UUID) | Nil = nil, parent : T.class = T.class)

Instance methods

next

Returns the next element in this iterator, or Iterator::Stop::INSTANCE if there are no more elements.

on

Method expects a block which will get invoked with Change(T) parameter on change events received from EventBus

stop

Shortcut for Iterator::Stop::INSTANCE, to signal that there are no more elements in an iterator.
