Core Decorators
core-decorators 是一个 JavaScript 类装饰器库和框架实用程序，用于扩展类功能。它提供了一系列工具，用于实现类行为混入 (mixins)、自动绑定方法以避免手动构造函数配置，以及验证子类方法是否正确覆盖父类方法。
该库包括一个代码弃用工具包，用于通过控制台警告标记过时的方法，以及一个用于测量性能和持续时间的函数执行分析器。它进一步通过自定义装饰器和共享逻辑注入系统，实现了对类和方法行为的修改。
其他功能涵盖对象属性控制，包括强制执行只读属性和限制属性可见性。该工具包还提供性能原语，例如结果缓存和延迟属性初始化，以将执行推迟到首次访问时。
Features
- Behavioral Injection - Provides a comprehensive system of decorators for injecting shared behaviors and custom logic into JavaScript classes.
- Class Mixins - Implements class behavior mixins to inject shared functionality from multiple sources into a single target class.
- Override Validations - Ensuring that subclass methods correctly override parent methods to prevent accidental naming collisions or signature mismatches.
- Automatic Context Binding - Automatically binds class methods to their instances to ensure the correct context is maintained during callbacks.
- Function Context Binding - Provides utilities to permanently bind the this context to class instances for consistent function execution.
- Function Decorators - Allows wrapping methods with custom helper functions or third-party utilities to augment their behavior.
- Object Method Binding - Automatically associates class methods with their respective instances to avoid manual constructor binding.
- General Purpose Mixins - Implements reusable class fragments to inject shared behavior across diverse class hierarchies.
- Higher-Order Function Wrapping - Augments method behavior by wrapping original functions with helper logic for profiling, caching, or warning suppression.
- Class Decorators - Provides a collection of class decorators to modify and extend the behavior of JavaScript classes and methods.
- Automatic Method Binding - Ensures class methods maintain a permanent reference to the class instance without requiring manual constructor binding.
- API Deprecation Tooling - Marks outdated methods as deprecated to warn developers and guide them toward newer API alternatives.
- Override Enforcement - Verifies that subclass methods correctly override parent class methods to ensure architectural integrity.
- Override Validation - Verifies that subclass methods correctly override parent class methods to prevent naming collisions and signature mismatches.
- Override Verification - Verifies that subclass methods correctly override parent methods to prevent naming collisions and signature mismatches.
- Deprecated Feature Markings - Provides a mechanism to flag methods as obsolete to warn developers through console warnings.
- Lazy Property Initialization - Implements deferred property initialization to delay execution and reduce memory allocations until first access.
- Method Wrapping - Applies external functions and arguments to a method to wrap it with custom logic.
- Property Descriptors - Manipulates property descriptors to control the enumerability, writability, and configurability of class members.
- Object Property Descriptor Controls - Enforces stricter data integrity by restricting property visibility and marking class members as read-only.
- API Deprecation Notifications - Emits custom console warnings and URLs when deprecated methods are invoked to notify developers.
- Developer Deprecation Warnings - Provides a toolkit for flagging obsolete methods with console warnings to guide developers during codebase migration.
- Function Execution Timing - Tracks the elapsed time of function execution using console timing labels to identify bottlenecks.
- Function Execution Timers - Measures the execution time of functions using browser console timers via decorators.
- Performance Profilers - Triggers browser profiling using console timers for single runs or specific time intervals.
- Performance Profiling - Includes tools to monitor execution time and resource usage to identify performance bottlenecks.
