Enclosing class:

Resolver

public abstract static class Resolver.Action
extends Object

An abstract class for an action to be taken to resolve a writer's schema (found in public instance variable writer) against a reader's schema (in reader). Ordinarily, neither field can be null, except that the reader field can be null in a Resolver.Skip, which is used to skip a field in a writer's record that doesn't exist in the reader's (and thus there is no reader schema to resolve to).
