Owning Palette: Variant VIs and Functions

Requires: Base Development System. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.

Use the Data Type Parsing VIs to retrieve and compare the data type stored in a variant to other data types.

Palette ObjectDescription
Check for Contained Data TypeReturns TRUE if Variant contains the data type you specify.
Disconnect Type DefinitionsReturns the data type stored in Variant in and removes all connections to type definitions from the data type.
Get Array InformationRetrieves array information from the data type stored in Variant. This VI only accepts variants that contain the array data type.
Get Cluster InformationRetrieves cluster information from the data type stored in Variant. This VI only accepts variants that contain the cluster data type.
Get Fixed-Point InformationRetrieves fixed-point numeric (FXP) information from the data type stored in Variant. This VI only accepts variants that contain the fixed-point numeric data type.
Get LabVIEW Class InformationRetrieves LabVIEW class information from the data type stored in Variant. This VI only accepts variants that contain a LabVIEW class.
Get Numeric InformationRetrieves numeric information from the data type stored in Variant. This VI only accepts variants that contain the numeric data type.
Get Polymorphic VI InformationRetrieves polymorphic VI information from the data type stored in Variant. This VI only accepts variants that contain polymorphic VI information.
Get Refnum InformationRetrieves refnum information from the data type stored in Variant. This VI only accepts variants that contain a refnum.
Get Tag InformationReturns the tag data type stored in Variant. This VI only accepts variants that contain a tag.
Get Type Definition PathReturns the path to the type definition of the data type stored in Variant.
Get Type InformationRetrieves data type information from the data type stored in Variant.
Get User-Defined Refnum InformationRetrieves user-defined refnum information from the data type stored in Variant. This VI only accepts variants that contain a user-defined refnum.
Get User-Defined Tag InformationRetrieves user-defined tag information from the data type stored in Variant. This VI only accepts variants that contain a user-defined tag.
Get VI InformationRetrieves VI information from the data type stored in Variant. This VI only accepts variants that contain VI information.
Get Waveform InformationRetrieves waveform information from the data type stored in Variant. This VI only accepts variants that contain a waveform.
Is or Contains Type DefinitionReturns TRUE if the data type stored in Variant is an instance of a type definition or contains a data type which is an instance of a type definition.
