  Description
  AbstractCharacterFilterReader
  A filter reader that filters out characters where subclasses decide which characters to filter out.
  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.
  AutoCloseInputStream.Builder
  Builds a new `AutoCloseInputStream` instance.
  BOMInputStream
  This class is used to wrap a stream that includes an encoded `ByteOrderMark` as its first bytes.
  BOMInputStream.Builder
  Builds a new `BOMInputStream`.
  BoundedInputStream
  Reads bytes up to a maximum count and stops once reached.
  BoundedInputStream.Builder
  Builds a new `BoundedInputStream`.
  BrokenInputStream
  Always throws an exception from all `InputStream` methods where `IOException` is declared.
  BrokenReader
  Always throws an exception from all `Reader` methods where `IOException` is declared.
  BufferedFileChannelInputStream
  `InputStream` implementation which uses direct buffer to read a file to avoid extra copy of data between Java and native memory which happens when using `BufferedInputStream`.
  BufferedFileChannelInputStream.Builder
  Builds a new `BufferedFileChannelInputStream`.
  CharSequenceInputStream
  Implements an `InputStream` to read bytes from String, StringBuffer, StringBuilder or CharBuffer, encoded using the specified Charset.
  CharSequenceInputStream.Builder
  Builds a new `CharSequenceInputStream`.
  ChecksumInputStream
  Automatically verifies a `Checksum` value once the stream is exhausted or the count threshold is reached.
  ChecksumInputStream.Builder
  Builds a new `ChecksumInputStream`.
  CircularInputStream
  An `InputStream` that repeats provided bytes for given target byte count.
  ClosedInputStream
  Always returns `IOUtils.EOF` to all attempts to read something from the stream.
  ClosedReader
  Always returns `IOUtils.EOF` to all attempts to read something from it.
  CloseShieldInputStream
  Proxy stream that prevents the underlying input stream from being closed.
  CloseShieldReader
  Proxy reader that prevents the underlying reader from being closed.
  CountingInputStream
  Deprecated.
  Use `BoundedInputStream` (unbounded by default).
  MemoryMappedFileInputStream
  An `InputStream` that utilizes memory mapped files to improve performance.
  MemoryMappedFileInputStream.Builder
  Builds a new `MemoryMappedFileInputStream`.
  MessageDigestCalculatingInputStream
  Deprecated.
  Use `MessageDigestInputStream`.
  MessageDigestCalculatingInputStream.Builder
  Deprecated.
  Builds a new `MessageDigestCalculatingInputStream`.
  MessageDigestInputStream
  This class is an example for using an `ObservableInputStream`.
  MessageDigestInputStream.Builder
  Builds new `MessageDigestInputStream`.
  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.
  ObservableInputStream
  The `ObservableInputStream` allows, that an InputStream may be consumed by other receivers, apart from the thread, which is reading it.
  ObservableInputStream.Observer
  Abstracts observer callback for `ObservableInputStream`s.
  ProxyInputStream
  A proxy stream which acts as a `FilterInputStream`, by passing all method calls on to the proxied stream, not changing which methods are 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.
  QueueInputStream
  Simple alternative to JDK `PipedInputStream`; queue input stream provides what's written in queue output stream.
  QueueInputStream.Builder
  Builds a new `QueueInputStream`.
  RandomAccessFileInputStream
  Streams data from a `RandomAccessFile` starting at its current position.
  RandomAccessFileInputStream.Builder
  Builds a new `RandomAccessFileInputStream`.
  ReadAheadInputStream
  Implements `InputStream` to asynchronously read ahead from an underlying input stream when a specified amount of data has been read from the current buffer.
  ReadAheadInputStream.Builder
  Builds a new `ReadAheadInputStream`.
  ReaderInputStream
  `InputStream` implementation that reads a character stream from a `Reader` and transforms it to a byte stream using a specified charset encoding.
  ReaderInputStream.Builder
  Builds a new `ReaderInputStream`.
  ReversedLinesFileReader
  Reads lines in a file reversely (similar to a BufferedReader, but starting at the last line).
  ReversedLinesFileReader.Builder
  Builds a new `ReversedLinesFileReader`.
  Tailer
  Simple implementation of the UNIX "tail -f" functionality.
  Tailer.Builder
  Builds a new `Tailer`.
  Tailer.RandomAccessResourceBridge
  Bridges access to a resource for random access, normally a file.
  Tailer.Tailable
  A tailable resource like a file.
  TailerListener
  Listener for events from a `Tailer`.
  ThrottledInputStream
  Provides bandwidth throttling on a specified InputStream.
  ThrottledInputStream.Builder
  Builds a new `ThrottledInputStream`.
  UncheckedBufferedReader
  A `BufferedReader` that throws `UncheckedIOException` instead of `IOException`.
  UncheckedBufferedReader.Builder
  Builds a new `UncheckedBufferedReader`.
  UncheckedFilterInputStream
  A `BufferedReader` that throws `UncheckedIOException` instead of `IOException`.
  UncheckedFilterInputStream.Builder
  Builds a new `UncheckedFilterInputStream`.

  A `FilterReader` that throws `UncheckedIOException` instead of `IOException`.
  UncheckedFilterReader.Builder
  Builds a new `UncheckedFilterReader`.
  UnsynchronizedBufferedInputStream
  An unsynchronized version of `BufferedInputStream`, not thread-safe.
  UnsynchronizedByteArrayInputStream
  This is an alternative to `ByteArrayInputStream` which removes the synchronization overhead for non-concurrent access; as such this class is not thread-safe.
  UnsynchronizedByteArrayInputStream.Builder
  Builds a new `UnsynchronizedByteArrayInputStream`.
  UnsynchronizedFilterInputStream
  An unsynchronized version of `FilterInputStream`, not thread-safe.
  UnsynchronizedFilterInputStream.Builder
  Builds a new `UnsynchronizedFilterInputStream`.
  XmlStreamReader
  Character stream that handles all the necessary Voodoo to figure out the charset encoding of the XML document within the stream.
