Convert to Superclass Value

If an enumeration class specifies a superclass, convert an enumeration object to the

superclass by passing the object to the superclass constructor. However, the superclass

constructor must be able to accept its own class as input and return an instance of the

superclass. MATLAB built-in numeric classes, such as uint32, allow this conversion.

For example, the Bearing class derives from the uint32 built-in class:

classdef Bearing < uint32

enumeration

North (0)

East (90)

South (180)

West (270)

end

end

Assign the Bearing.East member to the variable a:

a = Bearing.East;

Pass a to the superclass constructor and return a uint32 value:

b = uint32(a);

a 1x1 60 Bearing

b 1x1 4 uint32

The uint32 constructor accepts an object of the subclass Bearing and returns and

object of class uint32.
