🏭 Model Factories in TuskLang Java

"We don't bow to any king" - Build factories like a Java architect

TuskLang Java provides sophisticated model factories that integrate seamlessly with Spring Boot, JPA, and modern Java patterns. Create, configure, and manage your data models with enterprise-grade factory patterns.

🎯 Overview

Model factories in TuskLang Java combine the power of Java factory patterns with TuskLang's configuration system. From JPA entity factories to Spring Boot service factories, we'll show you how to build robust, scalable model creation systems.

🔧 Core Factory Features

1. JPA Entity Factories

import javax.persistence.*;
import java.util.Map;
@Entity
@Table(name = "users")

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    
    @Column(nullable = false)
    private String name;
    
    @Column(unique = true, nullable = false)
    private String email;
    
    @Column(name = "created_at")
    private java.time.LocalDateTime createdAt;
    
    // Constructors, getters, setters
    public User() {}
    
    public User(String name, String email) {
        this.name = name;
        this.email = email;
        this.createdAt = java.time.LocalDateTime.now();
    }
    
    // Getters and setters
    public Long getId() { return id; }
    public void setId(Long id) { this.id = id; }
    
    public String getName() { return name; }
    public void setName(String name) { this.name = name; }
    
    public String getEmail() { return email; }
    public void setEmail(String email) { this.email = email; }
    
    public java.time.LocalDateTime getCreatedAt() { return createdAt; }
    public void setCreatedAt(java.time.LocalDateTime createdAt) { this.createdAt = createdAt; }

🔧 Spring Boot Integration

1. Spring Boot Configuration

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.tusklang.java.TuskLang;
import org.tusklang.java.spring.TuskFactoryConfig;
@SpringBootApplication
@Configuration
public class FactoryApplication {
    
    @Bean
    public TuskFactoryConfig tuskFactoryConfig() {
        TuskLang parser = new TuskLang();
        return parser.parseFile("factories.tsk", TuskFactoryConfig.class);
    }
    
    public static void main(String[] args) {
        SpringApplication.run(FactoryApplication.class, args);
    }
}
@TuskConfig
public class TuskFactoryConfig {
    private EntityFactoryConfig entityFactories;
    private ServiceFactoryConfig serviceFactories;
    private RepositoryFactoryConfig repositoryFactories;
    private DTOFactoryConfig dtoFactories;
    
    // Getters and setters
    public EntityFactoryConfig getEntityFactories() { return entityFactories; }
    public void setEntityFactories(EntityFactoryConfig entityFactories) { this.entityFactories = entityFactories; }
    
    public ServiceFactoryConfig getServiceFactories() { return serviceFactories; }
    public void setServiceFactories(ServiceFactoryConfig serviceFactories) { this.serviceFactories = serviceFactories; }
    
    public RepositoryFactoryConfig getRepositoryFactories() { return repositoryFactories; }
    public void setRepositoryFactories(RepositoryFactoryConfig repositoryFactories) { this.repositoryFactories = repositoryFactories; }
    
    public DTOFactoryConfig getDtoFactories() { return dtoFactories; }
    public void setDtoFactories(DTOFactoryConfig dtoFactories) { this.dtoFactories = dtoFactories; }
}

🎯 Best Practices

1. Factory Design Patterns

// ✅ Use appropriate factory patterns
- Simple Factory: For basic object creation
- Factory Method: For complex object creation
- Abstract Factory: For related object families
- Builder: For complex object construction
// ✅ Implement validation in factories
- Validate input parameters
- Check business rules
- Ensure data integrity
// ✅ Use dependency injection
- Inject dependencies into factories
- Use Spring Boot's DI container
- Maintain loose coupling
// ✅ Implement caching strategies
- Cache frequently created objects
- Use appropriate cache eviction policies
- Monitor cache performance

2. Performance Optimization

// 1. Factory Caching
- Cache factory instances
- Cache created objects when appropriate
- Use appropriate cache sizes
// 2. Lazy Initialization
- Initialize factories on demand
- Use lazy loading for heavy objects
- Implement proper cleanup
// 3. Resource Management
- Properly manage database connections
- Clean up resources after use
- Use try-with-resources
// 4. Validation Optimization
- Validate early and often
- Use efficient validation rules
- Cache validation results

🚀 Summary

TuskLang Java model factories provide:

- JPA Entity Factories: Seamless JPA integration with validation - Spring Boot Service Factories: Native Spring Boot service creation - Repository Factories: Custom repository patterns with optimized queries - DTO Factories: Efficient data transfer object creation - Abstract Factory Patterns: Complex object family creation - Builder Pattern Integration: Fluent API for complex object construction - Spring Boot Integration: Native Spring Boot configuration support

With these factory features, your Java applications will achieve enterprise-grade model creation while maintaining the flexibility and power of TuskLang configuration.
