Table Data Gateway Generator

GenerateTableDataGatewayAttribute creates a typed InMemoryTableDataGateway<TRow,TKey> factory from a key selector method.

[GenerateTableDataGateway(typeof(OrderTableRow), typeof(string), FactoryName = "CreateGateway", TableName = "orders")]
public static partial class GeneratedOrderTableGateway
{
    [TableGatewayKeySelector]
    private static string SelectKey(OrderTableRow row) => row.OrderId;
}

The generated factory is equivalent to:

InMemoryTableDataGateway<OrderTableRow, string>
    .Create("orders", SelectKey)
    .Build();

Diagnostics:

• PKTDG001: host type must be partial.
• PKTDG002: exactly one [TableGatewayKeySelector] method is required.
• PKTDG003: key selector must be static and return TKey from one TRow parameter.
