Class WriterOutputStream

  • All Implemented Interfaces:
    java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable
    public class WriterOutputStream
extends java.io.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.
