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.
|Superclass of all handle classes|
|Provide handle classes with set and get methods|
|Require exact name match for set and get methods|
|Superclass for classes that support dynamic properties|
|Superclass providing copy functionality for handle objects|
|Create event listener bound to event source|
|Create event listener without binding to event source|
|Notify listeners that event is occurring|
|Delete handle object|
|Find handle objects|
|Determine valid handles|
|Determine equality or sort handle objects|
Characteristics of Handle and Value Classes
- Comparison of Handle and Value Classes
Value objects are associated with a specific variable. Handle objects can be referenced by multiple variables.
- Which Kind of Class to Use
Whether you implement a handle or value class depends on what your class represents and how you want objects to behave.
- Handle Object Behavior
MATLAB® handle variables support reference semantics.
Building on the Handle Class
- The Handle Superclass
handleclass 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.
Working with Handle Classes
- Find Handle Objects and Properties
Find objects using regular expressions or obtain the
meta.propertyobject for specific properties.
- Implement Set/Get Interface for Properties
Create a set/get interface for your handle class.
- Implement Copy for Handle Classes
Customize object copy operations by deriving from the
- Handle Compatible Classes
Enable both handle and value classes to derive from a specific class.
