# Package org.apache.avro.hadoop.io

Class Summary
AvroDatumConverter<INPUT,OUTPUT>: Converts a Java object into an Avro datum.
AvroDatumConverterFactory: Constructs converters that turn objects (usually from the output of a MR job) into Avro data that can be serialized.
AvroDatumConverterFactory.AvroWrapperConverter: Converts AvroWrappers into their wrapped Avro data.
AvroDatumConverterFactory.BooleanWritableConverter: Converts BooleanWritables into Booleans.
AvroDatumConverterFactory.BytesWritableConverter: Converts BytesWritables into ByteBuffers.
AvroDatumConverterFactory.ByteWritableConverter: Converts ByteWritables into GenericFixed of size 1.
AvroDatumConverterFactory.DoubleWritableConverter: Converts DoubleWritables into Doubles.
AvroDatumConverterFactory.FloatWritableConverter: Converts FloatWritables into Floats.
AvroDatumConverterFactory.IntWritableConverter: Converts IntWritables into Ints.
AvroDatumConverterFactory.LongWritableConverter: Converts LongWritables into Longs.
AvroDatumConverterFactory.NullWritableConverter: Converts NullWritables into Nulls.
AvroDatumConverterFactory.TextConverter: Converts Text into CharSequences.
AvroDeserializer<T extends AvroWrapper<D>,D>: Deserializes AvroWrapper objects within Hadoop.
AvroKeyComparator<T>: The `RawComparator` used by jobs configured with `AvroJob`.
AvroKeyDeserializer<D>: Deserializes AvroKey objects within Hadoop.
AvroKeyValue<K,V>: A helper object for working with the Avro generic records that are used to store key/value pairs in an Avro container file.
AvroKeyValue.Iterator<K,V>: A wrapper for iterators over GenericRecords that are known to be KeyValue records.
AvroSequenceFile: A wrapper around a Hadoop `SequenceFile` that also supports reading and writing Avro data.
AvroSequenceFile.Reader: A reader for SequenceFiles that may contain Avro data.
AvroSequenceFile.Reader.Options: A helper class to encapsulate the options that can be used to construct a Reader.
AvroSequenceFile.Writer: A writer for an uncompressed SequenceFile that supports Avro data.
AvroSequenceFile.Writer.Options: A helper class to encapsulate the options that can be used to construct a Writer.
AvroSerialization<T>: The `Serialization` used by jobs configured with `AvroJob`.
AvroSerializer<T>: Serializes AvroWrapper objects within Hadoop.
AvroValueDeserializer<D>: Deserializes AvroValue objects within Hadoop.
