Interface CoderTranslator<T extends Coder<?>>

@Experimental(value=CORE_RUNNERS_ONLY)
public interface CoderTranslator<T extends Coder<?>>

An interface that translates coders to components and back.

This interface is highly experimental, and incomplete. Coders must in the general case have the capability to encode an additional payload, which is not currently supported. This exists as a temporary measure.

Method Summary
