    Typecasts a class object or class reference to a class below the object or reference in the inheritance hierarchy.

    You can use this node to typecast any object or reference in a class hierarchy, including VI Server references, .NET/ActiveX references, and classes you create.

    connector_pane_image
    datatype_icon

    reference

    Class reference or class object you want to typecast to a target class within the inheritance hierarchy.

    datatype_icon

    target class

    Class you want reference to match.

    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

    specific class reference

    Class reference or class object typecast to the target class.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.

    Typecasting Classes

    Typecasting changes the data type of an input to that of the class you specify. This allows you to access the object or reference you input as if it is the target class you specify.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported

    Web Server: Not supported in VIs that run in a web application
