Syntax

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Interface, Inherited = false, AllowMultiple = true)]
public class DatabaseClassValidation : DatabaseValidation

Remarks

You can mark this attribute against a class, referring to a custom validation like so:

public interface IMyClass { }

[DatabaseClassValidation(typeof(MyCustomValidation), nameof(MyCustomValidation.test))]
public class MyClass : IMyClass
{

}

public static class MyCustomValidation
{
    public static Task<ValidationResult> ValidateMyClass(IMyClass item, LemonEdge.Core.IEntityUpdater dbCon, LemonEdge.Entities.IReadOnlyCache cache, LemonEdge.API.Core.UserInfo user, ValidationContext validationContext)
    {
        //Custom checks here
        return Task.FromResult(ValidationResult.Success);
    }
}

Constructors
