Hudsxn Introspection
====================

[](#hudsxn-introspection)

Hudsxn Introspection is a **high-performance PHP library** for full-depth class, interface, and trait introspection. It captures **properties, constants, methods, method arguments, and attributes** while supporting **memory caching**, **filesystem-backed caching**, and selective or full refresh modes. Ideal for frameworks, static analysis tools, IDE integrations, and any system that requires reliable reflection metadata.

---

Features
--------

[](#features)

- Deep introspection of **classes, interfaces, and traits**
- **Memory caching** for repeated accesses
- **Filesystem caching** to persist introspection results across requests
- **Refresh mode** to regenerate metadata when source changes
- **Selective refresh** to optimize performance in large systems
- Singleton-based introspector for centralized caching and consistent results
- Fully **tested** and production-ready

---

Installation
------------

[](#installation)

Install via Composer:

```
composer require hudsxn/introspection
```

---

Basic Usage
-----------

[](#basic-usage)

```
use Hudsxn\Introspection\Introspector;

// Get singleton instance
$introspector = Introspector::getSelf();

// Initialize with cache directory
$introspector->init(__DIR__ . '/cache');

// Set mode (fastest in-memory caching)
$introspector->setMode(Introspector::MODE_FASTEST);

// Introspect a class
$classObj = $introspector->getClass(MyApp\ExampleClass::class);

// Access properties
foreach ($classObj->getProperties() as $property) {
    echo $property->getName() . ': ' . $property->getType() . PHP_EOL;
}

// Access methods and arguments
foreach ($classObj->getMethods() as $method) {
    echo $method->getName() . '(): ' . $method->getReturnType() . PHP_EOL;
    foreach ($method->getArguments() as $arg) {
        echo '  - ' . $arg->getName() . ': ' . $arg->getType() . PHP_EOL;
    }
}
```

---

Refresh Modes
-------------

[](#refresh-modes)

- **Default:** Uses memory and filesystem caches
- **Refresh:** Regenerates class metadata from source
- **Selective Refresh:** Only refresh specific classes

```
// Refresh a single class
$introspector->setMode([\MyApp\ExampleClass::class]);
$refreshedClass = $introspector->getClass(MyApp\ExampleClass::class);
```

---

Filesystem Cache
----------------

[](#filesystem-cache)

- The library can **persist introspected metadata to disk** for faster repeated access.
- Clearing memory cache does **not remove filesystem cache**, so subsequent requests will load cached PHP files.

```
// Clear only memory cache
$introspector->clearInstanceCache();

// Clear memory + filesystem cache
$introspector->clearCache();
```

---

Performance Benefits
--------------------

[](#performance-benefits)

OperationWithout CacheWith Memory CacheWith Filesystem CacheFirst introspection100% parsing overheadN/AN/ASecond introspection100% parsingNear-instantNear-instantSubsequent request after memory clear100% parsingN/ANear-instant (loaded from disk)- **Memory cache** ensures repeated accesses are **nearly instantaneous**.
- **Filesystem cache** avoids repeated reflection parsing across processes.
- Works seamlessly for **hundreds of classes** with negligible overhead.

---

---

Testing
-------

[](#testing)

Run full test suite:

```
composer install
vendor/bin/phpunit
```

- The library is fully tested for **memory caching, filesystem caching, refresh modes**, and **deep introspection** of classes, interfaces, and traits.
- Tests validate that cached files maintain **100% fidelity** with native PHP reflection.

---

Contributing
------------

[](#contributing)

Contributions are welcome! Please submit pull requests or open issues on GitHub.

- Follow PSR-12 coding standards
- Include tests for new features or fixes
- Ensure **cache and introspection integrity**
