Sophisticated domain subentities creation methods

[pmrogala]

The golden sample

the source generator should have possibility to generate as follows: Source:

public class Aggregate
{
     public Entity Entity  { get; set; }
     public IEnumerable<Entity> Entities  { get; set; }
}

public class Entity
{
    /*    */
}

[MakeBuilder(typeof(Aggregate), <NewOption?>)]
[<NewAttribute?>]
public partial class AggregateBuilder
{
}

Output:

public partial class AggregateBuilder
{
     private Entity _entity;
     public AggregateBuilder WithEntity(Func<EntityBuilder, EntityBuilder> configureEntity)
     {
            _entity = configureEntity(new EntityBuilder());
            return this;
     }
     private IEnumerable<Entity> _entities;
     public AggregateBuilder WithEntities(params Func<EntityBuilder, EntityBuilder>[] configureEntities)
     {
            _entities = configureEntities.Select(x => x(new EntityBuilder()));
            return this;
     }
}

Detecting entities to generate methods

Namespace rule

To prevent generating wrongly builders for build-in types, or types from external libraries, the buildenator will detect subentities by the same root namespace of the parent entity.

e.x. this is correct:

NameSpaceRoot.Aggregate
NameSpaceRoot.SubNamespace.Entity

this is not correct:

NameSpaceRoot.Aggregate
SubNamespace.Entity

Filtering out value types

By default if the subentity has only one not sophisticated property/contr. parameter, it will be treated as a value type, so default methods will be created.

Configurability

• UseSubentityBuilders[True/False]: whether using subentity builders [False by default]
  • Should have possibility to set up a global config

[pmrogala]

The problem is with the subentities builders naming, how the aggregateRoot builder generator would know the names to generate? Probably this feature will require to implement #18 first.
