All Implemented Interfaces:

Closeable, AutoCloseable, Iterable<T>, FromFileReader<T>

public final class DataReader<T>
extends Object
implements FromFileReader<T>

A DataInput based FromFileReader. You have to construct and supply a custom DataReader.Deserializer instance to use this reader.

close

public void close()

Throws:

IOException

read

public T read()

Description copied from interface: FromFileReader

Returning null indicates that there are no more items to read. That's the same behaviour as BufferedReader.readLine(). All implementations must return null precisely once.

Specified by:
