Those objects are generated via the C<to> method of the L<Dancer2::Plugin::WebSocket::Connection> |
79
|
|
|
|
|
|
|
objects, and allow to easily send to groups of connections. |
80
|
|
|
|
|
|
|
|
81
|
|
|
|
|
|
|
In addition to any channels one might fancy creating, each connection also has a private |
82
|
|
|
|
|
|
|
channel that is associated to its numerical id, and a global channel C<*> also exist |
83
|
|
|
|
|
|
|
to send messages to all connections. |
