public class AvroTypeInfo<T extends org.apache.avro.specific.SpecificRecordBase>
extends PojoTypeInfo<T>

Special type information to generate a special AvroTypeInfo for Avro POJOs (implementing SpecificRecordBase, the typed Avro POJOs) Proceeding: It uses a regular pojo type analysis and replaces all GenericType with a GenericType. All other types used by Avro are standard Java types. Only strings are represented as CharSequence fields and represented as Utf8 classes at runtime. CharSequence is not comparable. To make them nicely usable with field expressions, we replace them here by generic type infos containing Utf8 classes (which are comparable), This class is checked by the AvroPojoTest.
