Functions

add_out_node(pid, new_out)

attributes()

child_spec(arg)

Returns a specification to start this module under a supervisor

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

get_category()

get_default_config()

get_name()

get_state(pid)

handle_msg(msg, state)

handle_msg/2 is called whenever the node receives a message from another node. It should return an {outgoing_msg, new_state} tuple

node_init(state)

node_init/1 initializes the node process. This is called as the last step of the node’s init function. Needs to return a new state or a {state, timeout} tuple. (see GenServer documentation)

add_out_node(pid, new_out)

attributes()

child_spec(arg)

Returns a specification to start this module under a supervisor.

See Supervisor.

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.

For an example of how to use it see the Trigger node.
