Get Type Information
Retrieves data type information from a variant.
variant
Variant data from which you want to retrieve data type information.
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
type
Data type stored in the variant.
G Type?
A Boolean value that indicates whether the data type stored in the variant is an instance of a G type.
| True |
The data type stored in the variant is an instance of a G type. |
| False |
The data type stored in the variant is not an instance of a G type. |
An Alternative Way to Detect a G Type
You also can use the Is or Contains G Type? node to determine whether the data type in the variant is an instance of a G type or contains a data type that is an instance of a G type. However, the Is or Contains G Type? node does not return the G type name.
error out
Error information.
The node produces this output according to standard error behavior.

G Type name
Name of the G type. This output returns an empty string if the data type stored in the variant is not an instance of a G type.
