loadobj

Modify load process for object

Syntax

b = loadobj(a)

Description

b = loadobj(a) is called by the load function if the class of a defines a loadobj method. load returns b as the value loaded from a MAT-file.

Define a loadobj method when objects of the class require special processing when loaded from MAT-files. If you define a saveobj method, then define a loadobj method to restore the object to the desired state. Define loadobj as a static method so it can accept as an argument whatever object or structure that you saved in the MAT-file. See Implement loadobj as a Static Method.

When loading a subclass object, load calls only the subclass loadobj method. If a superclass defines a loadobj method, the subclass inherits this method. However, it is possible that the inherited method does not perform the necessary operations to load the subclass object. Consider overriding superclass loadobj methods.

If any superclass in a class hierarchy defines a loadobj method, then the subclass loadobj method must ensure that the subclass and superclass objects load properly. Ensure proper loading by calling the superclass loadobj (or other methods) from the subclass loadobj method. See Saving and Loading Objects from Class Hierarchies.

Input Arguments

a

The input argument, a, can be:

  • The object as loaded from the MAT-file.

  • A structure created by load (if load cannot resolve the object).

  • A struct returned by the saveobj method.
