2.1. NotifyInterface

  1. Description

    • This is an attribute that creating INotifyPropertyChanged automatically.

    • Partial type declaration is required for using this attribute.

    • Supports class, record, struct.

    • Input and generated code looks like followings:

      // Input

[NotifyInterface]
public partial class CodeTest
{
}

      // Generated

public partial class CodeTest : INotifyPropertyChanged
{
    public event PropertyChangedEventHandler? PropertyChanged;

    protected virtual void OnPropertyChanged(PropertyChangedEventArgs e)
    {
        PropertyChanged?.Invoke(this, e);
    }

    protected void OnPropertyChanged([CallerMemberName] string? propertyName = null)
    {
        OnPropertyChanged(new PropertyChangedEventArgs(propertyName));
    }
}

2.2. Property

  1. Members

    Type Name Description
    string? CustomName Sets the custom name of property
    NotifyType NotifyType Sets the property's notification type

  2. Description

    • This attribute creates a property using given field as backing field.

    • Partial type declaration is required for using this attribute.

    • By default, Notify type is NotifyType.Notify.

    • Input and generated code looks like followings:

      // Input

public partial class CodeTest
{
    [Property]
    private bool _testBool = false;
}

      // Generated

public partial class CodeTest
{
    public bool TestBool
    {
        get => _testBool;
        set
        {
            if(_testBool != value)
            {
                _testBool = value;
                OnPropertyChanged(nameof(TestBool));
                OnTestBoolChanged();
            }
        }
    }

    partial void OnTestBoolChanged();
}

    • User could change property's name and its notification type.

      // Input

public partial class CodeTest
{
    [Property(CustomName = "MyProp", NotifyType = NotifyType.None)]
    private bool _testBool = false;
}

      // Generated

                _testBool = value;
                OnMyPropChanged();
            }
        }
    }

    partial void OnMyPropChanged();
}

}

      // Generated

public partial class CodeTest
{
    public bool MyProp
    {
        get
        {
            MyMethod(TestBool, FieldA);
            return _testBool;
        }
        set
        {
            if(_testBool != value)
            {
                _testBool = value;
                OnMyPropChanged();
                OtherMethod(TestBool, FieldB);
                TestCommand.RaiseCanExecuteChanged();
                OnPropertyChanged(nameof(TestParam));

    GrpcServerAttribute GrpcServer(GrpcServerMode) Default constructor

  3. Description

    • Use this attribute for mapping gRPC services.

    • Static class GrpcServerMapper will be generated in namespace Peponi.SourceGenerators.Grpc.

    • User could use GetStandaloneServices() or MapClientFactoryServices(IEndpointRouteBuilder) in GrpcServerMapper

    • Input and generated code looks like followings:

      // Generated by Protobuf compiler

namespace ServerContext
{
    public static partial class HelloWorld
    {
        public static ServerServiceDefinition BindService(HelloWorldBase base)
        {
        }

        public abstract partial class HelloWorldBase
        {
        }
    }
}

      • GrpcServerMode.Standalone

        // Input

namespace GeneratorTest
{
    [GrpcServer(GrpcServerMode.Standalone)]
    public class CodeTest : HelloWorld.HelloWorldBase
    {
    }
}

        // Generated

using Grpc.Core;

namespace Peponi.SourceGenerators.Grpc;

public static partial class GrpcServerMapper
{
    public static List<ServerServiceDefinition> GetStandaloneServices()
    {
        List<ServerServiceDefinition> rtns = new();
        rtns.Add(global::ServerContext.HelloWorld.BindService(new global::GeneratorTest.CodeTest()));
        return rtns;
    }
}

      • GrpcServerMode.ClientFactory

        // Input

namespace GeneratorTest
{
    [GrpcServer(GrpcServerMode.ClientFactory)]
    public class CodeTest : HelloWorld.HelloWorldBase
    {
    }
}

        // Generated

using Microsoft.AspNetCore.Routing;

namespace Peponi.SourceGenerators.Grpc;

public static partial class GrpcServerMapper
{
    public static IEndpointRouteBuilder MapClientFactoryServices(IEndpointRouteBuilder builder)
    {
        builder.MapGrpcService<global::GeneratorTest.CodeTest>();
        return builder;
    }
}

    • As a result, user could use GrpcServer attribute like followings:

      // GrpcServerMode.Standalone

using Peponi.SourceGenerators.Grpc;

public class Program
{
    private static void Main(string[] args)
    {
        var server = new Server()
        {
            Ports = { new ServerPort("localhost", 9091, ServerCredentials.Insecure) }
        };
        GrpcServerMapper.GetStandaloneServices().ForEach(server.Services.Add);

        server.Start();
    }
}

      // GrpcServerMode.ClientFactory

using Peponi.SourceGenerators.Grpc;

public class Program
{
    private static void Main(string[] args)
    {
        CreateHostBuilder().Build().Run();
    }

    private static IHostBuilder CreateHostBuilder() =>
        Host.CreateDefaultBuilder()
            .ConfigureWebHostDefaults(webBuilder =>
            {
                // Configure kestrel ...
                webBuilder.UseStartUp<StartUp>();
            });
}

public class StartUp
{
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddGrpc();
    }

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        // Configure settings ...
        app.UseEndpoints(endpoints =>
        {
            endpoints = GrpcServerMapper.MapClientFactoryServices(endpoints);
        });
    }
}
