public interface CodecProvider

A provider of Codec instances. Typically, an instance of a class implementing this interface would be used to construct a CodecRegistry.

While the CodecProvider interface adds no stipulations to the general contract for the Object.equals, programmers who implement the CodecProvider interface "directly" must exercise care if they choose to override the Object.equals. It is not necessary to do so, and the simplest course of action is to rely on Object's implementation, but the implementer may wish to implement a "value comparison" in place of the default "reference comparison."
