  DNSOverHTTPS	Simple implemetation of DNS over HTTPS.
  EepGet	EepGet [-p 127.0.0.1:4444] [-n #retries] [-o outputFile] [-m markSize lineLen] url
  EepHead	This is a quick hack to get a working EepHead, primarily for the following usage:
  EepPost	Extends EepGet for POST.
  EventDispatcherImpl	An implementation of the EventDispatcher interface.
  FileLogWriter	File-based log writer thread that pulls log records from the LogManager, writes them to the current logfile, and rotates the logs as necessary.
  FileSuffixFilter	A FileFilter that accepts regular files with a suffix and optionally a prefix, case-insensitive.
  FileUtil	General helper methods for messing with files These are static methods that do NOT convert arguments to absolute paths for a particular context and directory.
  FortunaRandomSource	Wrapper around GNU-Crypto's Fortuna PRNG.
  HexDump	Hexdump class (well, it's actually a namespace with some functions, but let's stick with java terminology :-).
  I2PAppThread	Like I2PThread but with per-thread OOM listeners, rather than a static router-wide listener list, so that an OOM in an app won't call the router listener to shutdown the whole router.
  I2PProperties	This class contains a number of properties ((key,value)-pairs).
  I2PSSLSocketFactory	Loads trusted ASCII certs from ~/.i2p/certificates/ and $I2P/certificates/.
  I2PThread	Preferred over Thread for all router uses.
  InternalServerSocket	A simple in-JVM ServerSocket using Piped Streams.
  InternalSocket	A simple in-JVM Socket using Piped Streams.
  KeyRing	Thread-safe mapping from router hashes to session keys.
  LHMCache<K,V>	A LinkedHashMap with a maximum size, for use as an LRU cache.
  Log	Wrapper class for whatever logging system I2P uses.
  LogConsoleBuffer	Offer a glimpse into the last few console messages generated.
  LogLimit	Defines the log limit for a particular set of logs
  LogManager	Manages the logging system, loading (and reloading) the configuration file, coordinating the log limits, and storing the set of log records pending.
  LogRecord	Keep track of a log entry, unformatted.
  LogRecordFormatter	Render a log record according to the log manager's settings
  LogWriter	Log writer thread that pulls log records from the LogManager and writes them to the log.
  LookaheadInputStream	Simple lookahead buffer to keep the last K bytes in reserve, configured to easily be reused.
  NativeBigInteger	BigInteger that takes advantage of the jbigi library for the modPow operation, which accounts for a massive segment of the processing cost of asymmetric crypto.
  ObjectCounter<K>	Thread-safe counter for tracking occurrences of objects.
  ObjectCounterUnsafe<K>	Non-thread-safe counter for tracking occurrences of objects.
  OrderedProperties	Properties map that has its keySet ordered consistently (via the key's lexicographical ordering).
  PartialEepGet	Fetch exactly the first 'size' bytes into a stream Anything less or more will throw an IOException No retries, no min and max size options, no timeout option If the server does not return a Content-Length header of the correct size, the fetch will fail.
  PasswordManager	Manage both plaintext and salted/hashed password storage in router.config.
  PortMapper	Map services to internal or external application ports for this context.
  RandomSource	Singleton for whatever PRNG i2p uses.
  ResettableGZIPInputStream	GZIP implementation per RFC 1952, reusing java's standard CRC32 and Inflater and InflaterInputStream implementations.
  ResettableGZIPOutputStream	GZIP implementation per RFC 1952, reusing java's standard CRC32 and Deflater implementations.
  ReusableGZIPInputStream	Provide a cache of reusable GZIP unzipper streams.
  ReusableGZIPOutputStream	Provide a cache of reusable GZIP streams, each handling up to 40 KB output without expansion.
  RFC822Date	Moved from NewsFetcher
  SecureDirectory	Same as File but sets the file mode after mkdir() so it can be read and written by the owner only (i.e.
  SecureFile	Same as SecureDirectory but sets the file mode after createNewFile() and createTempFile() also.
  SecureFileOutputStream	Same as FileOutputStream but sets the file mode so it can only be read and written by the owner only (i.e.
  ShellCommand	Passes a command to the OS shell for execution and manages the input and output.
  SimpleByteCache	Like ByteCache but works directly with byte arrays, not ByteArrays.
  SimpleTimer2	Scheduled event executor backed by ScheduledThreadPoolExecutor.
  SimpleTimer2.TimedEvent	Base class for timer events.
  SipHash	Wrapper around SipHashInline with constant per-JVM keys
  SocketTimeout	Implements one or two timers; one for inactivity, that is reset by resetTimer(), and optionally, a total time since instantiation, that is configured by setTotalTimeoutPeriod().
  SSLEepGet	HTTPS only, no retries, no min and max size options, no timeout option As of 0.9.45, supports redirect to https (redirect to http will still fail).
  SSLEepGet.SSLState	An opaque class for the caller to pass to repeated instantiations of SSLEepGet.
  SyntheticREDQueue	A "synthetic" queue that does not store data but estimates the average queue size assuming a fixed output bandwidth, and applies the Random Early Detection (RED) algorithm to decide probabilistically whether to accept or drop packets.
  SystemVersion	Methods to find out what system we are running on
  TempDirScanner	Prevent systemd from deleting our temp dir or any dirs or files in it.
  TimeoutPipedInputStream	Adds setReadTimeout().
  TimeoutPipedOutputStream	Helper for TimeoutPipedInputStream.
  Translate	Translate strings efficiently.
  TranslateReader	Translate.
  TryCache<T>	A thread-safe, lock-free-ish object cache that reuses objects to reduce allocation overhead.
  UIMessages	A queue of messages, where each has an ID number.
  UIMessages.Message	Represents a single UI message with a unique identifier.
  UnmodifiableSortedSet<E>	Efficient implementation of a SortedSet stored in a fixed-size array.
  VersionComparator	Compares versions.

• Exception Summary 

  Exception	Description
  ArraySet.SetFullException	Exception thrown when attempting to add an element to a full ArraySet.
