SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Delphi developers often struggle to create reusable, type-safe code when implementing collections and patterns like Repository or Nullable/Result.

Core Features & Use Cases

Generic declarations and constraints (class, interface, constructor)
Built-in generic collections usage: TList<T>, TDictionary<K,V>, TQueue<T>, TStack<T>
Common patterns: Repository<T>, Nullable<T>, Result<T,E>
Real-world examples and templates to accelerate Delphi projects

Quick Start

Declare a generic type or method in Delphi and apply constraints to guide usage.

FAQPage Schema

How do I implement generics with constraints in Delphi classes and methods?▼

Delphi generics constraints are applied using syntax like `class` or `constructor` to restrict type parameters. This Skill enables developers to declare generic types and methods, ensuring type-safe reusable code across classes and interfaces in Delphi projects.

What are the best ways to use generic collections like TList<T> and TDictionary<K,V> in Delphi?▼

Built-in Delphi generic collections like TList<T>, TDictionary<K,V>, TQueue<T>, and TStack<T> provide type-safe data storage. This Skill covers their practical usage with real-world examples to accelerate the implementation of reusable collection structures.

How do I design a Repository<T> pattern using Delphi generics?▼

The Repository<T> pattern in Delphi uses generics to create a reusable data access layer. This Skill provides templates and practical examples for implementing Repository<T>, Nullable<T>, and Result<T,E> patterns to handle data operations and error management safely.

When do I need Nullable<T> and Result<T,E> patterns in Delphi?▼

Nullable<T> handles missing values in Delphi generics, while Result<T,E> encapsulates operation outcomes and errors. This Skill demonstrates when to apply these patterns to build robust, type-safe logic without relying on exceptions for control flow.

Does Delphi support constructor constraints for generic type instantiation?▼

Delphi generic constraints support `constructor` to allow creating instances of the type parameter within generic methods. This Skill explains how to apply class, interface, and constructor constraints to guide generic type usage and enforce compile-time type safety.
