# BoxLang Classes and Object-Oriented Programming ## Overview BoxLang classes are defined in `.bx` files. A class is a blueprint that encapsulates properties (data) and functions/methods (behavior). BoxLang supports single inheritance, multiple interface implementation, abstract classes, and static members. ## Basic Class Structure ```boxlang // File: models/User.bx class accessors="true" { // Properties (auto-generates getters/setters when accessors="true") property name="firstName" type="string" property name="lastName" type="string" property name="email" type="string" property name="createdAt" type="date" // Constructor function init( required string firstName, required string lastName, required string email ) { variables.firstName = arguments.firstName variables.lastName = arguments.lastName variables.email = arguments.email variables.createdAt = now() return this } // Method string function getFullName() { return "#variables.firstName# #variables.lastName#" } } ``` ## Scopes Inside a Class | Scope | Access | Use | |-------|--------|-----| | `variables` | Private | Internal state, private methods | | `this` | Public | Public methods exposed to callers | | `static` | Class-level | Shared across all instances | ## Instantiation ```boxlang // Using `new` var user = new models.User( "Ada", "Lovelace", "ada@example.com" ) // Using createObject var user = createObj
