SafeMapper
=============

[![Build status](https://ci.appveyor.com/api/projects/status/skkynthpqot0bmo4?svg=true)](https://ci.appveyor.com/project/unger/safemapper) [![Coverage Status](https://coveralls.io/repos/unger/SafeMapper/badge.svg)](https://coveralls.io/r/unger/SafeMapper)

The goal with SafeMapper is to have an exception free and extremly fast mapper between primitive and complex types.

The project is influenced by AutoMapper, EmitMapper and FastMapper.

##Key features

- High speed performance
- Map between primitive types and string
- Map array and collections
- Exception free conversion between most types, fallback to default value for the type
- Support for both Structs and Classes
- Support for nested objects
- Support for public Fields and Properties
- Support for interfaces IEnumerable<T>, IList<T>, ICollection<T> etc
- Enum conversion to and from int and string
- Support for Enums with DisplayAttribute/DescriptionAttribute
- Conversion from NameValueCollection to Object
- Conversion from Object to NameValueCollection
- Mapping support to and from IDictionary&lt;string, T&gt;
- Simple circular reference check on type-level
- Configuration support to enable mapping fields/properties with different names

##Installation

http://nuget.org/packages/SafeMapper/

Install-Package SafeMapper

##Usage

The fastest way is to get a converter delegate and reuse that if you should convert many objects

var person = new Person();
    var converter = SafeMap.GetConverter<Person, PersonDto>();
    var personDto = converter(person);

But it is also possible to call Convert directly

var person = new Person();
    var personDto = SafeMap.Convert<Person, PersonDto>(person);

By default members with the same names are mapped to each other, but this can be configured before calling the convert method. It is also possible to configure mapping between properties/fields and methods.

SafeMap.CreateMap<Person, PersonDto>(
        cfg =>
        {
            cfg.Map(x => x.Id, x => x.PersonId);
            cfg.Map(x => x.GetName(), x => x.PersonName);
            cfg.Map(x => x.Length, (x, v) => x.SetPersonLength(v));
            cfg.Map(x => x.Age, "PersonAge");
        });

##Speed test

Converting 100000 objects between CustomerDto and Customer, see SafeMapper.Tests.Model for definition

SafeMapper:     13.7 ms
    EmitMapper:     17.0 ms
    FastMapper:    142.1 ms
    ValueInjector: 337.3 ms
    AutoMapper:   2092.0 ms

##Planned features

- Full Support for circular references between objects
- Support for flattening
- Plugin support to extend core functionality (Converters and Membermapping etc)
- Map from Database queries to c# object
- Map Lucene documents to c# object
