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 Object | Description |
|---|---|
| Check for Contained Data Type | Returns TRUE if variant contains the data type you specify. |
| Disconnect Type Definitions | Returns the data type stored in variant in and removes all connections to type definitions from the data type. |
| Get Array Information | Retrieves array information from the data type stored in variant. This VI returns an error if variant does not contain an array. |
| Get Channel Information | Retrieves channel information from the data type stored in variant. This VI returns an error if variant does not contain a channel. |
| Get Cluster Information | Retrieves cluster information from the data type stored in variant. This VI returns an error if variant does not contain a cluster. |
| Get Fixed-Point Information | Retrieves fixed-point numeric (FXP) information from the data type stored in variant. This VI returns an error if variant does not contain a fixed-point numeric. |
| Get LabVIEW Class Information | Retrieves LabVIEW class information from the data type stored in variant. This VI returns an error if variant does not contain a LabVIEW class. |
| Get LabVIEW Class Parent And Member VI Information | Retrieves parent and member VI information of the LabVIEW class or interface stored in variant. This VI returns an error if variant does not contain a LabVIEW class or interface or if the LabVIEW class or interface is broken due to missing parents or missing private data control dependencies. |
| Get Map Collection Information | Retrieves map information from the data type stored in variant. |
| Get Numeric Information | Retrieves numeric information from the data type stored in variant. This VI returns an error if variant does not contain a numeric. |
| Get Polymorphic VI Information | Retrieves polymorphic VI information from the data type stored in variant. This VI returns an error if variant does not contain a polymorphic VI. |
| Get Refnum Information | Retrieves refnum information from the data type stored in variant. This VI returns an error if variant does not contain a refnum. |
| Get Set Collection Information | Retrieves set information from the data type stored in variant. |
| Get Tag Information | Returns the tag data type stored in variant. This VI returns an error if variant does not contain a tag. |
| Get Type Definition Path | Returns the path to the type definition of the data type stored in variant. |
| Get Type Information | Retrieves data type information from the data type stored in variant. |
| Get User-Defined Refnum Information | Retrieves user-defined refnum information from the data type stored in variant. This VI returns an error if variant does not contain a user-defined refnum. |
| Get User-Defined Tag Information | Retrieves user-defined tag information from the data type stored in variant. This VI returns an error if variant does not contain a user-defined tag. |
| Get VI Information | Retrieves VI information from the data type stored in variant. This VI returns an error if variant does not contain a VI. |
| Get Waveform Information | Retrieves waveform information from the data type stored in variant. This VI returns an error if variant does not contain a waveform. |
| Is Error Cluster | Indicates whether the data type stored in variant is an error cluster. |
| Is or Contains Type Definition | Returns 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. |
