MATLAB Object-Oriented Programming

Clear the class to reload the definition of the HandleColors class:

clear classes

a = HandleColors.Red;

a.R

ans =

1

To prevent reassignment of a given property value, set that property's SetAccess

attribute to immutable.

Equality of Handle-Based Enumerations

Assign two variables to a particular enumeration member:

a = HandleColors.Red;

b = HandleColors.Red;

Compare a and b using isequal:

isequal(a,b)

ans =

1

The property values of a and b are the same, so isequal returns true. However, unlike

handle classes that are not enumeration classes, a and b are the same handle because

there is only one enumeration member. Determine handle equality using == (the handle

eq method).

a == b

ans =

1

See the handle eq method for information on how isequal and == differ when used

with handles.
