Object Save and Load - MATLAB & Simulink (original) (raw)
Customize the object save and load process
MATLAB® provides default behavior for using theload and save functions with objects, but you can customize the process of serializing (saving) and deserializing (loading) objects using one of two approaches:
- Recommended: Inherit from matlab.mixin.CustomElementSerialization (since R2024b).
- Implement saveobj andloadobj methods.
See When to Customize the Serialization Process for more information.
Classes
| matlab.mixin.CustomElementSerialization | Customize how objects are serialized and deserialized (Since R2024b) |
|---|---|
| matlab.serialization.ElementSerializationContent | Representation of serialized object (Since R2024b) |
| matlab.serialization.SerializationContext | Context in which objects are serialized (Since R2024b) |
Functions
| saveobj | Customize save process for objects |
|---|---|
| loadobj | Customize load process for objects |

Default Behavior for save and load with Objects
- Default Save and Load Process for Objects
MATLAB follows some default guidelines to serialize (save) and deserialize (load) objects. - Avoid Property Initialization Order Dependency
Avoid initialization order dependency by defining set methods for dependent properties.
Customize Object Serialization
- When to Customize the Serialization Process
Modify the save and load process for objects. - Maintain Backward and Forward Compatibility Between Class Definitions
Modify the save and load process to provide class version compatibility. - Serialization with Class Hierarchies
Subclasses can callmatlab.mixin.CustomElementSerializationmethods of their superclasses. - Transitioning Serialization and Deserialization Processes to matlab.mixin.CustomElementSerialization
Consider transitioning tomatlab.mixin.CustomElementSerializationfrom olderloadobjandsaveobjimplementations. - Code Patterns for saveobj and loadobj
Use these patterns to implement custom save and load processes usingsaveobjandloadobj.
