Propiedades

Declaración de propiedades, atributos y métodos de acceso

Las propiedades contienen datos de objetos. Las clases definen las mismas propiedades para todo el objeto, pero cada objeto puede tener valores de datos únicos. Los atributos de las propiedades controlan qué funciones o métodos pueden acceder a la propiedad. Es posible definir funciones que se ejecuten cada vez que se definan o consulten valores de propiedades. Las propiedades pueden activar eventos cuando el código acceda a sus valores.

Métodos de acceso a propiedades

  • Property Access Methods
    Property access methods execute code when property values are referenced or assigned. Implementing these methods enables you to control what actions occur when values are set or queried.
  • Property Set Methods
    Property set methods must follow specific syntax and execution rules.
  • Property Get Methods
    Property get methods must follow specific syntax and execution rules.
  • Set and Get Methods for Dependent Properties
    Dependent properties need access methods because these properties do not store values. Property access methods manage interactions with the dependent properties.
