const mixinafBedSheet::ValueEncoder

Implement to convert values to and from Str objects. Contribute it to the ValueEncoders service.

ValueEncoders are responsible for converting Strs from request uri segments into request handler method arguments.

In general, Fantom objects use toStr() and fromStr() for Str conversion. While this works well for serialisation, it often falls short in the context of a web application. This is because in an application, the object in question is often an entity or DTO from a database, and you need services to create it... which you don't have in a static fromStr() ctor!

Therefore ValueEncoders allow you to use the standard afIoc dependency injection and any service of your choice.
