Classdef

Supported FeaturesEdit

PropertiesEdit

Classdef properties are supported but not all attributes are implemented.

Attribute Support Notes
AbortSet No Property does not exist.
Abstract Yes
Access Partial
Constant Yes
Dependent Partial
GetAccess Partial
GetObservable No Property exists but is not used. Requires events and listeners to be implemented in order to work properly.
Hidden Yes
NonCopyable No Property does not exist.
SetAccess Partial
SetObservable No Property exists but is not used. Requires events and listeners to be implemented in order to work properly.
Transient No Property exists but is not used.

MethodsEdit

Classdef methods are supported but not all attributes are fully implemented.

Attribute Support Notes
Abstract Partial See bug report #51377
Access Yes
Hidden Yes
Sealed Yes
Static Yes
