Generate User Event (G Dataflow)

Version:
    Last Modified: March 15, 2017

    Broadcasts the user event you wire to this node and associated event data to each Event Structure registered to handle the event.

    If the event is not registered, this node has no effect.

    user event

    User event refnum created by a Create User Event node.

    datatype_icon

    event data

    The type of data you defined in the user event data type input of the Create User Event node. The data type of the event data input must match the data type of the user event. For example, if the data type of the user event input is a string, the data type of the event data input must also be a string.

    datatype_icon

    priority

    Value that defines how this node enqueues the user event.

    Name Description
    high priority Enqueues the user event and associated event data into the event queue in front of any previously generated normal priority events.
    normal priority Enqueues the user event and associated event data into the event queue behind any previously generated events.

    Default: (0) high priority

    datatype_icon

    error in

    Error conditions that occur before this node runs.

    The node responds to this input according to standard error behavior.

    Standard Error Behavior

    Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

    error in does not contain an error error in contains an error
    If no error occurred before the node runs, the node begins execution normally.

    If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

    If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

    Default: No error

    datatype_icon

    user event out

    The resulting user event reference.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.
