Handle Classes

Classes can support reference or value semantics

Create the appropriate type of class for your application:

  • Value classes enable you to create new array classes that have the same semantics as numeric classes.

  • Handle classes define objects that reference the object. Copying an object creates another reference to the same object.

For a discussion of how object users work with handle objects, see Handle Object Behavior.

Characteristics of Handle and Value Classes

Building on the Handle Class

  • The Handle Superclass
    The handle class implements methods to support events and listeners, destructors, relational operations, and other operations.
  • Handle Class Destructor
    Define a delete method to customize what happens when MATLAB destroys handle objects.
