add_out_node(pid, new_out)

attributes()

child_spec(arg)

Returns a specification to start this module under a supervisor

daemon_child_specs(config)

daemon_child_specs/1 needs to return a list of child specs. These child processes will be started under the DaemonNodeSupervisor

fire(state)

fire/1 is called when the user clicks on the play button on a node in the UI (and with that triggers a ‘fire’ event). It should return a new_state

attributes()

child_spec(arg)

Returns a specification to start this module under a supervisor.

See Supervisor.

daemon_child_specs(config)

daemon_child_specs/1 needs to return a list of child specs. These child processes will be started under the DaemonNodeSupervisor.

Callback implementation for Exred.NodePrototype.daemon_child_specs/1.

fire(state)

fire/1 is called when the user clicks on the play button on a node in the UI (and with that triggers a ‘fire’ event). It should return a new_state.

Since this has access to the node’s state it can be used to implement user triggered actions like logging the state, sending messages from the node or creating debug events that are displayed in the debug tab in the UI.
