org.jline.utils.WriterOutputStream

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

public class WriterOutputStream
extends OutputStream

Redirects an OutputStream to a Writer by decoding the data using the specified Charset.

Note: This class should only be used if it is necessary to redirect an OutputStream to a Writer for compatibility purposes. It is much more efficient to write to the Writer directly.
