Class DependencyInjection

java.lang.Object
dev.demeng.pluginbase.di.DependencyInjection
public final class DependencyInjection extends Object
Utility class for creating and working with dependency injection containers.

This class provides convenient static methods for creating DependencyContainer instances.

Example usage: 


 // Create services
 DatabaseConnection db = new MySQLConnection(plugin);
 CacheService cache = new RedisCacheService();

 // Create a container with interface-based registration
 DependencyContainer container = DependencyInjection.builder()
     .register(plugin)  // Register by concrete type
     .register(DatabaseConnection.class, db)  // Register by interface
     .register(CacheService.class, cache)     // Register by interface
     .build();

 // Classes annotated with @Component will be auto-created:
 @Component
 public class PlayerDataManager {
   private final DatabaseConnection db;
   private final CacheService cache;

   public PlayerDataManager(DatabaseConnection db, CacheService cache) {
     this.db = db;
     this.cache = cache;
   }
 }

 // Retrieve auto-created components
 PlayerDataManager manager = container.getInstance(PlayerDataManager.class);

 // Or create an empty container
 DependencyContainer container = DependencyInjection.create();

      Use the builder to configure bindings, register types, and register singleton instances before building the container.

      Returns:
      A new DependencyContainer.Builder instance

    • create

      @NotNull public static @NotNull DependencyContainer create()

      Returns:
      A new DependencyContainer instance
