close

public void close()
           throws java.io.IOException

Specified by:

close in interface java.lang.AutoCloseable

Specified by:

close in interface java.io.Closeable

Specified by:

close in interface FromFileReader<T>

Throws:

java.io.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:
