Typecasts a class object to a class you specify if both are in the same inheritance hierarchy.
Class object whose class you want object in to match.
Class object whose class you want to typecast to that of target object.
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.
Default: No error
Class object of the same class as target object.
Error information.
The node produces this output according to standard error behavior.

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.
If you wire a child class to a subVI that accepts and returns a parent class in the inheritance hierarchy, the subVI automatically typecasts the class output to the same child class as the input. However, the class output is not automatically typecast if the subVI cannot verify that the class data type of a wire does not change across the diagram. When the class data type of a wire does not change across the diagram of a subVI, use Preserve Run-Time Class to typecast the class output immediately before returning it from the subVI.
