Table of Property Attributes

All properties support the attributes listed in the following table. Attributes enable you to modify the behavior of properties. Attribute values apply to all properties defined within the properties block that specifies the nondefault values.

Attribute Name	Class	Description
`AbortSet`	logical default = `false`	If `true`, and this property belongs to a handle class, then MATLAB does not set the property value if the new value is the same as the current value. This approach prevents 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. See Controlling Property Access. Abstract properties cannot define initial values. See Assigning a Default Value. 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`	`char` default = `public`	`public` – unrestricted access `protected` – access from class or derived classes `private` – access by class members only 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. See Defining Named Constants for more information.
`Dependent`	logical default = `false`	If `false`, property value 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. See Dependent Properties, Property Get Methods, Avoiding Property Initialization Order Dependency
`GetAccess`	enumeration default = `public`	`public` — unrestricted access `protected` — access from class or derived classes `private` — access by class members only
`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. See Property-Set and Query Events
`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.).
`SetAccess`	enumeration default = `public`	`public` — unrestricted access `protected` — access from class or derived classes `private` — access by class members only
`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. See Property-Set and Query Events
`Transient`	logical default = `false`	If `true`, property value is not saved when object is saved to a file. See The Save and Load Process for more about saving objects.
