classdef MyClass < nelson.mixin.Copyable
b = copy(a)
| Parameter | Description |
|---|---|
| a | a handle object of a class deriving from nelson.mixin.Copyable. |
| Parameter | Description |
|---|---|
| b | an independent shallow copy of a. |
Derive a handle class from nelson.mixin.Copyable to give it a copy method that returns an independent shallow copy of an object.
copy(a) creates a new object and copies each property value from a. Properties declared NonCopyable are not copied and keep their default value in the copy. The copy is shallow: handle-valued properties are shared between the original and the copy.
nelson.mixin.Copyable is itself a handle class.
