Clases de identificadores
Clases de identificadores compatibles con la semántica de referencia
Un constructor de clases de identificadores devuelve un objeto identificador que es una referencia para el objeto creado. Puede asignar el objeto identificador a varias variables o pasarlo a funciones sin hacer que MATLAB® haga una copia del objeto original. Para ver un análisis más detallado acerca de cómo trabajar con objetos identificadores, consulte Comportamiento de los objetos de identificadores.
Funciones
isequal | Determine array equality |
eq | Determine equality |
matlab.lang.invalidHandle | Construct array of invalid handles (Desde R2024b) |
Clases
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 |
matlab.lang.WeakReference | Weak reference to handle object (Desde R2024b) |
matlab.lang.HandlePlaceholder | Basic subclass of handle (Desde R2024b) |
Métodos
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 |
Temas
Características de clases de identificadores y valores
- 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. - Comportamiento de los objetos de identificadores
Las variables de identificador de MATLAB admiten semántica de referencia.
Cómo aprovechar las clases de identificadores
- The Handle Superclass
Thehandleclass 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.
Trabajo con clases de identificadores
- Find Handle Objects and Properties
Find objects using regular expressions or obtain thematlab.metadata.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 thematlab.mixin.Copyableclass. - Handle Compatible Classes
Enable both handle and value classes to derive from a specific class. - Weak Reference Handles
Create weak references to handle classes. (Desde R2024b)
