NTraits

Portable library for attaching behaviours to objects at runtime using extension methods.

Installation:

Install-Package NTraits

Attaching a trait

     someObject.Traits().Add<SomeTraitType>(someTrait); //the trait will be registered using the generic method type

Checking for trait

     bool hasTrait = someObject.Has<SomeTraitType>(); //returns true or false

Checking for a trait, or the instance if it implements the requested type

     bool hasTrait = someObject.Has<SomeTraitType>(); 

Retreiving a trait, or the instance if it implements the requested type

     SomeTraitType trait = someObject.As<SomeTraitType>(); //will return null, or an instance of SomeTraitType

You can also cast back to any other trait on the traited entity, or back to the entity from a trait

     SomeTraitType trait = someObject.As<SomeTraitType>(); 
     
     SomeOtherTraitType otherTrait = trait.As<SomeOtherTraitType>(); 
     
     var originalSomeObject = otherTrait.As<SomeObject>(); 
     

Retreiving all traits attached to an object

     IEnumerable<object> traits = someObject.Traits(); //enumerable

Removing a trait

     bool removed = someObject.Traits().Pop<SomeTraitType>();
