Classi handle

Le classi possono supportare la semantica del riferimento o del valore

Creare il tipo di classe appropriato per l'applicazione:

Le classi valore consentono di creare nuove classi di array con la stessa semantica delle classi numeriche.
Le classi handle definiscono oggetti che referenziano object. La copia di un oggetto crea un altro riferimento allo stesso oggetto.

Per una discussione su come gli utenti degli oggetti lavorano con gli oggetti handle, vedere Handle Object Behavior.

Funzioni

`isequal`	Determine array equality
`eq`	Determine equality

`handle`	Superclass of all handle classes
`matlab.mixin.SetGet`	Provide handle classes with set and get methods
`matlab.mixin.SetGetExactNames`	Require exact name match for set and get methods
`dynamicprops`	Superclass for classes that support dynamic properties
`matlab.mixin.Copyable`	Superclass providing copy functionality for handle objects

`addlistener`	Create event listener bound to event source
`listener`	Create event listener without binding to event source
`notify`	Notify listeners that event is occurring
`delete`	Delete handle object
`findobj`	Find handle objects
`findprop`	Find `matlab.metadata.Property` object
`isvalid`	Determine valid handles
`relationaloperators`	Determine equality or sort handle objects

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.

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.

Find Handle Objects and Properties
Find objects using regular expressions or obtain the matlab.metadata.Property object 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 matlab.mixin.Copyable class.
Handle Compatible Classes
Enable both handle and value classes to derive from a specific class.
