NexusLabs.Needlr.Injection.SourceGen.TypeRegistrars ¶

GeneratedTypeRegistrar Class¶

A type registrar that uses compile-time generated type registry instead of runtime reflection for type discovery.

public sealed class GeneratedTypeRegistrar : NexusLabs.Needlr.Injection.ITypeRegistrar

Inheritance System.Object 🡒 GeneratedTypeRegistrar

Implements NexusLabs.Needlr.Injection.ITypeRegistrar

Example¶

// In your assembly (typically Program.cs or a dedicated file):
[assembly: GenerateTypeRegistry(IncludeNamespacePrefixes = new[] { "MyCompany", "NexusLabs" })]

// When building the service provider:
var serviceProvider = new Syringe()
    .UsingGeneratedTypeRegistrar()
    .BuildServiceProvider(config);

Remarks¶

This registrar is designed to work with the source generator from NexusLabs.Needlr.Generators. To use it: 1. Add the NexusLabs.Needlr.Generators package to your project 2. Add [assembly: GenerateTypeRegistry(...)] attribute 3. Use .UsingGeneratedTypeRegistrar() when building the service provider

The assemblies parameter is ignored when a type provider is supplied, as all type discovery happens at compile time.

Constructors¶

GeneratedTypeRegistrar() Constructor¶

Initializes a new instance using the default generated TypeRegistry.

public GeneratedTypeRegistrar();

Remarks¶

This constructor uses reflection to locate the generated TypeRegistry class. The generated class must be present in the calling assembly.

GeneratedTypeRegistrar(Func<IReadOnlyList<InjectableTypeInfo>>) Constructor¶

Initializes a new instance with a custom type provider.

public GeneratedTypeRegistrar(System.Func<System.Collections.Generic.IReadOnlyList<NexusLabs.Needlr.Generators.InjectableTypeInfo>>? typeProvider);

Parameters¶

typeProvider System.Func<System.Collections.Generic.IReadOnlyList<NexusLabs.Needlr.Generators.InjectableTypeInfo >>

A function that returns the injectable types. If null, the registrar will attempt to locate the generated TypeRegistry at runtime.

Methods¶

GeneratedTypeRegistrar.RegisterTypesFromAssemblies(IServiceCollection, ITypeFilterer, IReadOnlyList<Assembly>) Method¶

Registers types from the specified assemblies into the service collection.

public void RegisterTypesFromAssemblies(Microsoft.Extensions.DependencyInjection.IServiceCollection services, NexusLabs.Needlr.Injection.ITypeFilterer typeFilterer, System.Collections.Generic.IReadOnlyList<System.Reflection.Assembly> assemblies);
