Handle-Klassen

Klassen können Referenz- oder Wertesemantik unterstützen.

Erstellen Sie den angemessenen Klassentyp für Ihre Anwendung:

Werteklassen ermöglichen Ihnen, neue Array-Klassen zu erstellen, die dieselbe Semantik wie numerische Klassen aufweisen.
Handle-Klassen definieren Objekte, die das object referenzieren. Durch Kopieren eines Objekts wird eine andere Referenz auf dasselbe Objekt erstellt.

Weitere Informationen zur einer Diskussion über die Arbeitsweise mit Handle-Objekten durch Objekt-Benutzer finden Sie unter Handle Object Behavior.

Funktionen

`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.
