Supported Features
Properties
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. |
Methods
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 |
Features that are not implemented
enumeration
Octave should be able to parse the enumeration section of a classdef definition but nothing is done with it. Progress on this feature is tracked in bug report #44582.
events and listeners
Octave should be able to parse the events section of a classdef definition but nothing is done with it. Progress on this feature is tracked in bug report #56194.
