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

Get Type Information
Retrieves data type information from the data type stored in variant.
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 Cluster Information
Retrieves cluster information from the data type stored in variant. This VI returns an error if variant does not contain a cluster.
Is Error Cluster
Indicates whether the data type stored in variant is an error cluster.
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 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 Waveform Information
Retrieves waveform information from the data type stored in variant. This VI returns an error if variant does not contain a waveform.
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 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 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 Tag Information
Returns the tag data type stored in variant. This VI returns an error if variant does not contain a tag.
Get VI Information
Retrieves VI information from the data type stored in variant. To obtain the connector pane data type, read the Connector Pane:DataType property of the VI class in VI Server. This VI returns an error if variant does not contain a connector pane data type.
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 Map Collection Information
Retrieves map information from the data type stored in variant.
Get Set Collection Information
Retrieves set information from the data type stored in variant.
Get Type Definition Path
Returns the path to the type definition of the data type stored in variant.
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.
Disconnect Type Definitions
Returns the data type stored in variant in and removes all connections to type definitions from the data type.
Check for Contained Data Type
Returns TRUE if variant contains the data type you specify.
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.
