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);
}
}
