- **Adapter Pattern** - Logging adapters (`JclLoggerAdapter`, `JulLoggerAdapter`) for different logging frameworks
- **Template Method** - Resource traversal utilities with customizable handlers
- **Utility Classes** - All core functionality exposed through static utility methods for easy access

### Performance Optimizations
- **Caching** - Bean descriptors and reflection metadata are cached for improved performance

  // can reuse it.
  public static <E extends Enum<?> & Feature<?>> void assertGoodFeatureEnum(
      Class<E> featureEnumClass) {
    Class<?>[] classes = featureEnumClass.getDeclaredClasses();

      if (containedClass.getSimpleName().equals("Require")) {
        if (containedClass.isAnnotation()) {
          assertGoodTesterAnnotation(asAnnotation(containedClass));

 * <p>The core interface used to represent caches is {@link Cache}. In-memory caches can be
 * configured and created using {@link CacheBuilder}, with cache entries being loaded by {@link
 * CacheLoader}. Statistics about cache performance are exposed using {@link CacheStats}.

 * international domain names work everywhere. For example, "σ" encodes as "xn--4xa". The encoded
 * string is not human readable, but can be used with classes like [InetAddress] to establish
 * connections.

 * ## Why another URL model?
 *
 * Java includes both [java.net.URL][URL] and [java.net.URI][URI]. We offer a new URL
