Set Variant Attribute (G Dataflow)

Last Modified: January 12, 2018

Creates or replaces a variant attribute.

connector_pane_image
datatype_icon

variant

The variant data for which you want to create or replace an attribute value.

datatype_icon

name

The name of the attribute you want to replace or create. If name matches an attribute, this node replaces the attribute with the value specified. If name does not match an attribute, this node creates a new attribute. If name is an empty string, this node returns an error.

datatype_icon

value

The value of the attribute. You can wire any data type to this input.

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

variant out

The resulting variant data.

datatype_icon

replaced

A Boolean that indicates whether the node replaced an attribute.

True The node replaced an attribute.
False The node did not replace an attribute.
datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
