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.

Ways to Use Properties

There are different kinds of properties and each serves a different purpose.

Property Syntax

When you define properties, you also specify property attributes that control certain aspects of the property’s behavior.

Property Attributes

Attributes control the behavior of properties.

Property Access List

Specify a list of classes that can access a property.

Mutable and Immutable Properties

You can control what code can set property values.

Property Definition

Classes can assign default values to properties and you can change these values during object construction or direct access to the properties.

Define Class Properties with Constant Values

Use a class with Constant properties to define constant values

Properties Containing Objects

Properties assigned objects as default values construct that object only once when the class is first loaded. Also, assignment to contained object properties behaves differently depending on whether the object is a handle or value.

Validación de propiedades

Validate Property Values

You can restrict property values to a size and class, and apply functions to validate assigned values.

Property Class and Size Validation

Define class and size requirements for a property.

Property Validation Functions

Property validation functions enable you to check the values being assigned to properties.

Metadata Interface to Property Validation

Programmatically determine the size, class, and validation functions that validate the values assigned to properties.

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.
