AbortSet

logical

default = false

If true, MATLAB^® does not set the property value if the new value is the same as the current value and does not call the property set method, if one exists.

For handle classes, setting AbortSet to true also prevent the triggering of property PreSet and PostSet events.

Abstract

logical

default = false

If true, the property has no implementation, but a concrete subclass must redefine this property without Abstract being set to true.

• Abstract properties cannot define set or get access methods.

• Abstract properties cannot define initial values.

• All subclasses must specify the same values as the superclass for the property SetAccess and GetAccess attributes.

• Abstract=true use with the class attribute Sealed=false (the default).

Access

• enumeration, default = public

• meta.class object

• cell array of meta.class objects

public – unrestricted access

protected – access from class or subclasses

private – access by class members only (not subclasses)

List of classes that have get and set access to this property. Specify classes 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 private access.

Use Access to set both SetAccess and GetAccess to the same value. Query the values of SetAccess and GetAccess directly (not Access).

Constant

logical

default = false

Set to true if you want only one value for this property in all instances of the class:

• Subclasses inherit constant properties, but cannot change them.

• Constant properties cannot be Dependent.

• SetAccess is ignored.

Dependent

logical

default = false

If false, property value is stored in object. If true, property value is not stored in object. The set and get functions cannot access the property by indexing into the object using the property name.

MATLAB does not display in the command window the names and values of Dependent properties that do not define a get method (scalar object display only).

GetAccess

enumeration

default = public

public — unrestricted access

protected — access from class or subclasses

private — access by class members only (not from subclasses)

List classes that have get access to this property. Specify classes 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 private access.

MATLAB does not display in the command window the names and values of properties having protected or private GetAccess or properties whose Hidden attribute is true.

The struct function defines fields for all properties when converting objects to structs.

GetObservable

logical

default = false

If true, and it is a handle class property, then you can create listeners for access to this property. The listeners are called whenever property values are queried.

Hidden

logical

default = false

Determines whether the property should be shown in a property list (e.g., Property Inspector, call to set or get, etc.).

MATLAB does not display in the command window the names and values of properties whose Hidden attribute is true or properties having protected or private GetAccess.

SetAccess

enumeration

default = public

public — unrestricted access

protected — access from class or subclasses

private — access by class members only (not from subclasses)

immutable — property can be set only in the constructor.

List classes that have set access to this property. Specify classes 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 private access.

SetObservable

logical

default = false

If true, and it is a handle class property, then you can create listeners for access to this property. The listeners are called whenever property values are modified.

Transient

logical

default = false

If true, property value is not saved when object is saved to a file.
