Encamina.Enmarcha.Data.Abstractions 8.1.5

Data - Abstractions

This project mainly contains abstractions related to data used by other ENMARCHA NuGet packages or necessary for creating your own implementations.

Setup

Nuget package

First, install NuGet. Then, install Encamina.Enmarcha.Data.Abstractions from the package manager console:

PM> Install-Package Encamina.Enmarcha.Data.Abstractions

.NET CLI:

First, install .NET CLI. Then, install Encamina.Enmarcha.Data.Abstractions from the .NET CLI:

dotnet add package Encamina.Enmarcha.Data.Abstractions

How to use

In addition to the abstractions (interfaces, abstract classes, etc.) that have their implementations in other ENMARCHA NuGets, such as IFullUnitOfWork/FullUnitOfWork, you can create your own implementations.

public class InMemoryReadRepository<TEntity> : IReadRepository<TEntity> 
    where TEntity : IIdentifiable // IIdentifiable requires Encamina.Enmarcha.Entities.Abstractions nuget
{
    private readonly List<TEntity> entities = new();

    public IQueryable<TEntity> GetAll()
    {
        return entities.AsQueryable();
    }

    public IQueryable<TEntity> GetAll([NotNull] Func<IQueryable<TEntity>, IQueryable<TEntity>> queryFunction)
    {
        return entities.AsQueryable();
    }

    public TEntity GetById<TEntityId>(TEntityId id)
    {
        var entity = entities.FirstOrDefault(e => e.Id.Equals(id));
        if (entity == null)
        {
            throw new InvalidOperationException($"Entity with ID {id} not found.");
        }
        return entity;
    }
} 

This is example code, it is not tested. Do not use it in production.

In the previous example, an in-memory implementation of IReadRepository<TEntity> is created.
