Method Details

close

public void close()
           throws IOException

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Specified by:

close in interface FromFileReader<IN>

Throws:

IOException

read

public OUT 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:

read in interface FromFileReader<IN>
