Check for Contained Data Type (G Dataflow)

Version:
    Last Modified: August 28, 2017

    Checks whether a variant contains the data type you specify.

    connector_pane_image
    datatype_icon

    variant

    Variant data from which you want to retrieve data type information.

    datatype_icon

    data type to find

    Data type you want to find in the variant.

    datatype_icon

    check inside refnums

    A Boolean value that determines whether this node searches any refnums in the variant for the specified data type.

    True This node searches refnums in the variant for the specified data type.
    False This node does not search for the specified data type inside refnums.

    Default: False

    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

    LabVIEW class qualified name

    Specific class you want to find in the variant. You must set data type to find to Encapsulated to use this input.

    If you search for a class instance by setting data type to find to Encapsulated, but leave this input empty, contains data type to find? returns True when the variant contains any classes.

    datatype_icon

    contains data type to find?

    A Boolean value that indicates whether a variant contains the data type you want to find. This node also searches the data types of cluster or array elements.

    True The variant contains data type to find.
    False The variant does not contain data type to find.
    datatype_icon

    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
