# Package org.apache.commons.io.input

This package provides implementations of input classes, such as `InputStream` and `Reader`.

See: Description

- Interface Summary
  Interface | Description
  --- | ---
  TailerListener | Listener for events from a `Tailer`.

- Class Summary
  Class | Description
  --- | ---
  AutoCloseInputStream | Proxy stream that closes and discards the underlying stream as soon as the end of input has been reached or when the stream is explicitly closed.
  BOMInputStream | This class is used to wrap a stream that includes an encoded `ByteOrderMark` as its first bytes.
  BoundedInputStream | This is a stream that will only supply bytes up to a certain length - if its position goes above that, it will stop.
  BoundedReader | A reader that imposes a limit to the number of characters that can be read from an underlying reader, returning eof when this limit is reached -regardless of state of underlying reader.
  BrokenInputStream | Broken input stream.
  CharSequenceInputStream | `InputStream` implementation that can read from String, StringBuffer, StringBuilder or CharBuffer.
  CharSequenceReader | `Reader` implementation that can read from String, StringBuffer, StringBuilder or CharBuffer.
  ClassLoaderObjectInputStream | A special ObjectInputStream that loads a class based on a specified `ClassLoader` rather than the system default.
  ClosedInputStream | Closed input stream.
  CloseShieldInputStream | Proxy stream that prevents the underlying input stream from being closed.
  CountingInputStream | A decorating input stream that counts the number of bytes that have passed through the stream so far.
  DemuxInputStream | Data written to this stream is forwarded to a stream that has been associated with this thread.
  NullInputStream | A functional, light weight `InputStream` that emulates a stream of a specified size.
  NullReader | A functional, light weight `Reader` that emulates a reader of a specified size.
  ProxyInputStream | 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.
  ProxyReader | 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.
  ReaderInputStream | `InputStream` implementation that reads a character stream from a `Reader` and transforms it to a byte stream using a specified charset encoding.
  ReversedLinesFileReader | Reads lines in a file reversely (similar to a BufferedReader, but starting at the last line).
  SwappedDataInputStream | DataInput for systems relying on little endian data formats.
  TaggedInputStream | An input stream decorator that tags potential exceptions so that the stream that caused the exception can easily be identified.
  Tailer | Simple implementation of the unix "tail -f" functionality.
  TailerListenerAdapter | `TailerListener` Adapter.
  TeeInputStream | InputStream proxy that transparently writes a copy of all bytes read from the proxied stream to a given OutputStream.
  UnixLineEndingInputStream | A filtering input stream that ensures the content will have unix-style line endings, LF.
  WindowsLineEndingInputStream | A filtering input stream that ensures the content will have windows line endings, CRLF.
  XmlStreamReader | Character stream that handles all the necessary Voodo to figure out the charset encoding of the XML document within the stream.

- Exception Summary
  Exception | Description
  --- | ---
  XmlStreamReaderException | The XmlStreamReaderException is thrown by the XmlStreamReader constructors if the charset encoding can not be determined according to the XML 1.0 specification and RFC 3023.
