Tolitech.Domain.Specifications

Overview

Tolitech.Domain.Specifications implements the Specification pattern for .NET, enabling reusable, composable business rules and queries. It extends repository interfaces to support specification-based filtering and projections.

Features

  • Specification Pattern: Encapsulate business rules and queries as specifications.
  • Repository Extensions: Query entities using specifications and projections.
  • Async Operations: All repository methods are asynchronous.

Installation

Add a reference to the Tolitech.Domain.Specifications project or install via NuGet:

 dotnet add package Tolitech.Domain.Specifications

Usage

Specification Example

public class LegalAgeSpecification : Specification<Person>
{
    public override Expression<Func<Person, bool>> ToExpression() => p => p.Age >= 18;
}

Repository Query Example

var spec = new LegalAgeSpecification();
List<Person> adults = await repository.ToListAsync(spec, CancellationToken.None);

Projection Example

var spec = new LegalAgeSpecification();
List<string> names = await repository.ToListAsync(spec, p => p.Name, CancellationToken.None);

Count & Existence

bool anyAdults = await repository.AnyAsync(spec, CancellationToken.None);
int count = await repository.CountAsync(spec, CancellationToken.None);

Notes

  • Specifications can be combined for complex queries.
  • Integrates seamlessly with Tolitech.Domain entities and repositories.
