CodecRegistry class

Provides encoding and decoding services based on the ContentType of a Request or Response.

The defaultInstance provides a lookup table of ContentType to Codec. By default, 'application/json', 'application/x-www-form-urlencoded' and 'text/*' content types have codecs and can transform a Response.body into a list of bytes that can be transferred as an HTTP response body.

Additional mappings are added via add. This method must be called per-isolate and it is recommended to add mappings in an application's ApplicationChannel subclass constructor.
