Interface IIdGenerator

Interface for generating IDs for records in database. In general, IDs are just sequential numbers.

Namespace: Kros.Data

Assembly: Kros.Utils.dll

Syntax

public interface IIdGenerator : IDisposable

Remarks

Usually one generator generates IDs for just one table.

Examples

        public class PeopleService
    {
        private IIdGeneratorFactory _idGeneratorFactory;

        public PeopleService(IIdGeneratorFactory idGeneratorFactory)
        {
            _idGeneratorFactory = Check.NotNull(idGeneratorFactory, nameof(idGeneratorFactory));
        }

        public void GenerateData()
        {
            using (var idGenerator = _idGeneratorFactory.GetGenerator("people", 1000))
            {
                for (int i = 0; i < 1800; i++)
                {
                    var person = new Person()
                    {
                        Id = idGenerator.GetNext()
                    };
                }
            }
