close

public void close()

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Specified by:

close in interface FromFileReader<String>

Throws:

IOException

read

public String 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<String>

withFilteredParser

public <T> FromFileReader<T> withFilteredParser(TextLineReader.Parser<T> parser)

The filter is isLineOK(String)

withFilteredParser

public <T> FromFileReader<T> withFilteredParser(Predicate<String> filter,
 TextLineReader.Parser<T> parser)

The filter could for instance be isLineOK(String)

withParser

public <T> FromFileReader<T> withParser(TextLineReader.Parser<T> parser)
