PropertyHandlerMapper

A class that is being used to map a property handler into a .NET CLR type or a class property. This class is used as an alternative to the PropertyHandler attribute.

Please see the IPropertyHandler for more details about the property handling implementation.

Methods

Below is the list of methods.

Usability

Let us say you had implemented a System.DateTime handler like below.

public class DateTimeKindToUtcPropertyHandler : IPropertyHandler<DateTime?, DateTime?>
{
    public DateTime? Get(DateTime? input, PropertyHandlerGetOptions options)
    {
        return DateTime.SpecifyKind(input, DateTimeKind.Utc);
    }

    public DateTime? Set(DateTime? input, PropertyHandlerSetOptions options)
    {
        return DateTime.SpecifyKind(input.GetValueOrDefault(), DateTimeKind.Unspecified);
    }
}

Property Level Mapping

To add a property level mapping, simply call the Add() method and pass the target property and the instance of the property handler.

PropertyHandlerMapper.Add<Customer, DateTimeKindToUtcPropertyHandler>(e => e.DateOfBirth, new DateTimeKindToUtcPropertyHandler(), true);

An exception will be thrown if the mapping is already exists and you passed a false value in the force argument.

To get the mapping, use the Get() method.

var propertyHandler = PropertyHandlerMapper.Get<Customer, DateTimeKindToUtcPropertyHandler>(e => e.DateOfBirth);

To remove the mapping, use the Remove() method.

PropertyHandlerMapper.Remove<Customer, DateTimeKindToUtcPropertyHandler>(e => e.DateOfBirth);

Type Level Mapping

To add a class level mapping, simply call the type-level Add() method and pass the target .NET CLR type and the instance of property handler.

PropertyHandlerMapper.Add<DateTime, DateTimeKindToUtcPropertyHandler>(new DateTimeKindToUtcPropertyHandler(), true);

An exception will be thrown if the mapping is already exists and you passed a false value in the force argument.

To get the mapping, use the type-level Get() method.

var propertyHandler = PropertyHandlerMapper.Get<DateTime, DateTimeKindToUtcPropertyHandler>();

To remove the mapping, use the type-level Remove() method.

PropertyHandlerMapper.Remove<DateTime>();
