org.apache.hadoop.io.serializer.Deserializer.deserialize()

Deserialize the next object from the underlying input stream. If the object t is non-null then this deserializer may set its internal state to the next object read from the input stream. Otherwise, if the object t is null a new deserialized object will be created.
@return the deserialized object
