Class Resolver.WriterUnion

java.lang.Object

org.apache.avro.Resolver.Action

org.apache.avro.Resolver.WriterUnion

Enclosing class:

Resolver

public static class Resolver.WriterUnion
extends Resolver.Action

In this case, the writer was a union. There are two subcases here: If the reader and writer are the same union, then the unionEquiv variable is set to true and the actions list holds the resolutions of each branch of the writer against the corresponding branch of the reader (which will result in no material resolution work, because the branches will be equivalent). If they reader is not a union or is a different union, then unionEquiv is false and the actions list holds the resolution of each of the writer's branches against the entire schema of the reader (if the reader is a union, that will result in ReaderUnion actions).
