ProxyManager
ProxyManager is a JavaScript proxy wrapper library and object-oriented utility for intercepting and modifying object behavior. It functions as an object behavior interceptor that wraps target objects to monitor, restrict, or modify method calls and property access at runtime.
The library provides mechanisms for lazy initialization and lazy loading, deferring the creation of resource-heavy objects until a property or method is first accessed to reduce memory overhead. It uses an object-oriented structure to manage these proxy wrappers and their associated target objects.
The tool covers capabilities for dynamic access control and resource management optimization. It allows for the encapsulation of raw objects to implement custom execution logic and centralized access control.
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.
