Annotation Type SchemaFieldName

@Documented
 @Retention(value=RUNTIME)
 @Target(value={FIELD,METHOD})
public @interface SchemaFieldName

When used on a POJO field, a Java Bean getter, or an AutoValue getter, the specified name is used for the generated schema field.

For example, say we have a Java POJO with a field that we want in our schema but under a different name:

   @DefaultSchema(JavaFieldSchema.class)
   class MyClass {
     public String user;

     @SchemaFieldName("age")
     public int ageInYears;
   }
 

The resulting schema will have fields named "user" and "age."
