Get Notifier Status (G Dataflow)

Version:
    Last Modified: March 15, 2017

    Returns the last notification sent to the notifier and the number of nodes waiting on the notifier.

    Using this node in parallel code may result in race conditions. To avoid race conditions, use this node only for monitoring and not for controlling code.

    notifier

    A reference to a notifier.

    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

    notifier name

    The name of the notifier wired to notifier. If the notifier is not named, this is an empty string.

    datatype_icon

    notifier out

    Reference to the notifier.

    datatype_icon

    latest notification

    The most recent notification sent to the notifier.

    The data type of this output changes to match the data type of the notifier. If no notification has been sent, this node returns the default value for the data type of the notifier.

    datatype_icon

    number waiting

    The number of Wait on Notification, Wait on Notification from Multiple, Wait on Notification from Multiple with Notifier History, and Wait on Notification with Notifier History nodes that are currently waiting on the notifier.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.
