# Package org.apache.commons.io.output

This package provides implementations of output classes, such as `OutputStream` and `Writer`.

See: Description

- Class Summary
  Class | Description
  --- | ---
  AppendableOutputStream<T extends Appendable> | OutputStream implementation that writes the data to an `Appendable` Object.
  BrokenOutputStream | Broken output stream.
  ByteArrayOutputStream | This class implements an output stream in which the data is written into a byte array.
  ChunkedOutputStream | OutputStream which breaks larger output blocks into chunks.
  ChunkedWriter | Writer which breaks larger output blocks into chunks.
  ClosedOutputStream | Closed output stream.
  CloseShieldOutputStream | Proxy stream that prevents the underlying output stream from being closed.
  CountingOutputStream | A decorating output stream that counts the number of bytes that have passed through the stream so far.
  DeferredFileOutputStream | An output stream which will retain data in memory until a specified threshold is reached, and only then commit it to disk.
  DemuxOutputStream | Forwards data to a stream that has been associated with this thread.
  FileWriterWithEncoding | Writer of files that allows the encoding to be set.
  LockableFileWriter | FileWriter that will create and honor lock files to allow simple cross thread file lock handling.
  NullOutputStream | This OutputStream writes all data to the famous /dev/null.
  NullWriter | This `Writer` writes all data to the famous /dev/null.
  ProxyOutputStream | A Proxy stream which acts as expected, that is it passes the method calls on to the proxied stream and doesn't change which methods are being called.
  ProxyWriter | A Proxy stream which acts as expected, that is it passes the method calls on to the proxied stream and doesn't change which methods are being called.
  StringBuilderWriter | `Writer` implementation that outputs to a `StringBuilder`.
  TaggedOutputStream | An output stream decorator that tags potential exceptions so that the stream that caused the exception can easily be identified.
  TeeOutputStream | Classic splitter of OutputStream.
  ThresholdingOutputStream | An output stream which triggers an event when a specified number of bytes of data have been written to it.
  WriterOutputStream | `OutputStream` implementation that transforms a byte stream to a character stream using a specified charset encoding and writes the resulting stream to a `Writer`.
  XmlStreamWriter | Character stream that handles all the necessary Voodo to figure out the charset encoding of the XML document written to the stream.
