OLT Adapter Resolver and adapters for IQueryable and paged results

// Inject IOltAdapterResolver 


// Checks to see if can project IQueryable
adapterResolver.CanProjectTo<PersonEntity, PersonModel>(); 

//Simple Map
var person = adapterResolver.Map<PersonEntity, PersonModel>(entity, new PersonModel());


var queryable = Context.People.GetAll();
var records = adapterResolver.ProjectTo<PersonEntity, PersonModel>(queryable);

DI Configuration

Using https://www.nuget.org/packages/OLT.Utility.AssemblyScanner

var assemblies = new OltAssemblyScanBuilder()
 .IncludeFilter("OLT.", "MyApp.")
 .DeepScan()
 .ExcludeMicrosoft()
 .ExcludeNewtonsoft()
 .ExcludeAutomapper()
 .Build();

services.AddOltAdapters(opt => opt.AddAdapters(assemblies));

services.AddOltAutoMapper(opt =>
{
 opt.AddMaps(assemblies);
});

Simple Adapater

public class PersonEntityToPersonModelAdapter : OltAdapter<PersonEntity, PersonModel>
{
	public override void Map(PersonEntity source, PersonModel destination)
	{
		destination.Name = new PersonName
		{
			First = source.FirstName,
			Last = source.LastName,
		};
	}

	public override void Map(PersonModel source, PersonEntity destination)
	{
		destination.FirstName = source.Name.First;
		destination.LastName = source.Name.Last;
	}
}

Projection Adapter using IQueryable

public class PersonEntityToPersonModelQueryableAdapter : OltAdapter<PersonEntity, PersonModel>, IOltAdapterQueryable<PersonEntity, PersonModel>
{
	public PersonEntityToPersonModelQueryableAdapter()
	{
		this.WithOrderBy(p => p.OrderBy(o => o.FirstName).ThenBy(o => o.LastName));
	}

	public override void Map(PersonEntity source, PersonModel destination)
	{
		destination.Name = new PersonName
		{
			First = source.FirstName,
			Last = source.LastName,
		};
	}

	public override void Map(PersonModel source, PersonEntity destination)
	{
		destination.FirstName = source.Name.First;
		destination.LastName = source.Name.Last;
	}

	public IQueryable<PersonModel> Map(IQueryable<PersonEntity> queryable)
	{
		return queryable.Select(entity => new PersonModel
		{
			Name = new PersonName
			{
				First = entity.FirstName,
				Last = entity.LastName,
			}
		});
	}
}

Projection Adapter using IQueryable for Paging (requires Default Order By)

public class PersonEntityToPersonModelPagedAdapter : OltAdapterPaged<PersonEntity, PersonModel>
{
	public override void Map(PersonEntity source, PersonModel destination)
	{
		destination.Name = new PersonName
		{
		 First = source.FirstName,
		 Last = source.LastName,
		};
	}

	public override void Map(PersonModel source, PersonEntity destination)
	{
		destination.FirstName = source.Name?.First;
	 destination.LastName = source.Name?.Last;
	}

	public override IQueryable<PersonModel> Map(IQueryable<PersonEntity> queryable)
	{
		return queryable.Select(entity => new PersonModel
		{
			Name = new PersonName
			{
				First = entity.FirstName,
				Last = entity.LastName,
			}
		});
	}

	public override IOrderedQueryable<PersonEntity> DefaultOrderBy(IQueryable<PersonEntity> queryable)
	{
		return queryable.OrderBy(p => p.LastName).ThenBy(p => p.FirstName);
	}
}
