ProxyManager
ProxyManager es una biblioteca de envoltorio de proxy de JavaScript y utilidad orientada a objetos para interceptar y modificar el comportamiento de los objetos. Funciona como un interceptor de comportamiento de objetos que envuelve objetos objetivo para monitorear, restringir o modificar llamadas a métodos y acceso a propiedades en tiempo de ejecución.
La biblioteca proporciona mecanismos para la inicialización perezosa (lazy initialization) y carga perezosa (lazy loading), difiriendo la creación de objetos que consumen muchos recursos hasta que se accede por primera vez a una propiedad o método para reducir la sobrecarga de memoria. Utiliza una estructura orientada a objetos para gestionar estos envoltorios de proxy y sus objetos objetivo asociados.
La herramienta cubre capacidades para el control de acceso dinámico y la optimización de la gestión de recursos. Permite la encapsulación de objetos crudos para implementar lógica de ejecución personalizada y control de acceso centralizado.
Features
- Object Property Interceptors - Provides a wrapper to intercept and modify object property access and method calls at runtime.
- Method Interception Proxies - Implements a dynamic proxy system that intercepts method calls to inject custom behavior without altering the original source code.
- Lazy Initialization - Defers the instantiation of resource-heavy objects until their first access to improve startup performance.
- Lazy Loading - Implements mechanisms to defer the instantiation of resource-heavy objects until they are first accessed.
- JavaScript Proxy Libraries - Provides a library for intercepting and modifying object behavior using JavaScript Proxy objects.
- Proxy Objects - Wraps target objects in proxies to intercept and redefine fundamental runtime operations.
- Dynamic Behavior Injection - Provides the ability to modify how objects handle method calls and property access at runtime using JavaScript Proxies.
- Property Interception - Wraps target objects in a proxy to monitor and modify access to properties and method calls.
- Object Property Deferred Loading - Delays the creation of heavy resources until a specific method or property is requested to save memory.
- On-Demand Command Loading - Saves memory by delaying the creation of underlying objects until they are explicitly requested by the application.
- Lifecycle Management - Uses a class-based structure to organize and track the lifecycle of various proxy wrappers and their targets.
- Management Utilities - Offers an object-oriented structure to manage the lifecycle and organization of various proxy wrappers.
- Dynamic Object Access Control - Manages and restricts how specific properties or methods of an object are accessed or modified at runtime.
- Object Access Restrictions - Wraps target objects to monitor, restrict, or modify how specific properties and methods are accessed.
- Object Wrappers - Encapsulates raw objects within a proxy wrapper to implement access control and custom execution logic.
- Managed Proxy Layers - Builds object-oriented wrappers to intercept and extend the behavior of instances through a managed proxy layer.
- Proxy Interfaces - Hides raw objects behind a proxy interface to implement centralized access control and custom execution logic.
- Resource Initialization Optimization - Reduces system memory overhead by delaying the loading of expensive resources until the exact moment they are required.
- Database Interaction - Generates proxy objects for data mapping.
