klyn.io.TextReader.readLine
method

    public readLine() as String throws IOException

Description

Reads one line from the current reader position.

When a line terminator is present, it is part of the returned string. This follows Python-like `readline()` semantics and makes an empty line distinguishable from end-of-stream: an empty line returns `"\n"` (or `"\r\n"`), while end-of-stream returns `""`.

Returns

Next line including its line terminator when present, or `""` at end-of-stream.

Throws

- IOException if the resource is closed, inaccessible, not a valid file, or the underlying I/O operation fails.
