MATLAB Object-Oriented Programming

Class Attributes

Attribute Name Class Description

Abstract logical

(default =

false)

If specified as true, this class is an abstract class (cannot be

instantiated).

See “Abstract Classes” on page 12-91 for more information.

AllowedSubclasse

s

meta.class

object or cell

array of

meta.class

objects

List classes that can subclass this class. Specify subclasses

as meta.class objects in the form:

• A single meta.class object


• A cell array of meta.class objects. An empty cell array,
  {}, is the same as a Sealed class (no subclasses).

Specify meta.class objects using the ?ClassName syntax

only.

See “Specify Allowed Subclasses” on page 12-25 for more

information.

ConstructOnLoad logical

(default =

false)

If true, MATLAB calls the class constructor when loading an

object from a MAT-file. Therefore, implement the constructor

so it can be called with no arguments without producing an

error.

See “Initialize Objects When Loading” on page 13-30 for

more information.

HandleCompatible logical

(default =

false) for

value classes

If specified as true, this class can be used as a superclass

for handle classes. All handle classes are

HandleCompatible by definition. See “Handle Compatible

Classes” on page 12-39 for more information.

Hidden logical

(default =

false)

If true, this class does not appear in the output of the

superclasses or help functions.
