Delete Variant Attribute (G Dataflow)

Version:
Last Modified: August 28, 2017

Deletes either a single variant attribute or all variant attributes.

connector_pane_image
datatype_icon

variant in

The variant data for which you want to delete one or all attributes.

datatype_icon

names

The names of the attributes you want to delete. If names matches an attribute, this node deletes the attribute and its value. If names is an empty string, this node deletes all attributes in the variant data.

Default: all attributes

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 variant data with the deleted attribute(s).

datatype_icon

found?

A Boolean value that indicates whether the node found the attribute that is specified in name.

True The node found the attribute specified in name. If name is unwired, the node located and deleted all attributes.
False The node did not find the attribute specified in name. If name is unwired, the node found no attributes.

error out

Error information.

The node produces this output according to standard error behavior.

Where This Node Can Run:

Desktop OS: Windows

FPGA: This product does not support FPGA devices

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