Combinator.BeanFactory<T>
Combinator.CombinationAware
FutureListener<V>	FutureListener
Hasher<N,K>	Implementing this interface allows an object to customize how hash values are computed for Node objects and Key objects.
Hasher.HashAlgorithim	Used to calculate the hash of a binary buffer.
IOHelper.HardLinkStrategy
IOHelper.SyncStrategy
ListenableFuture<V>	ListenableFuture
Mapper<K,V>
Service	The core lifecyle interface for ActiveMQ components.
ServiceListener	A listener for service start, stop events
VoidFunction1<T1>

Class Summary

Class	Description
ApolloThreadPool	Holds a singleton instance to a cached thread pool that can be used to execute blocking tasks.
BitArray	Simple BitArray to enable setting multiple boolean values efficently Used instead of BitSet because BitSet does not allow for efficent serialization.
BitArrayBin	Holder for many bitArrays - used for message audit
BooleanEditor
ClassLoadingAwareObjectInputStream
Combinator	Combinator objects are used to compute all the possible combinations given a set of combination options.
Comparators
Hasher.BinaryHasher<N,K>	A Hasher implemenation which first convert the Node and Key to byte arrays before calculating the hash using a HashAlgorithim.
Hasher.MessageDigestFactory	A HashAlgorithim instance which use a MessageDigest algorithim to compute the hash value.
Hasher.Native	This Hasher implementation works with any type of object by using the Object.hashCode() method of the Node and Keys objects to compute the hash.
Hasher.ToStringCodec	Used to convert an object to a byte[] by basically doing: Object.toString().getBytes("UTF-8")
Hasher.ToStringHasher	This Hasher implementation works with any type of object by using Object.toString() and uses a checksum to compute the hash of the key and value.
HashList<E>
HashRing<Node,Resource>	A hash ring is used to map resources to a to a set of nodes.
IdGenerator	Generator for Globally unique Strings.
IndentPrinter	A helper class for printing indented text
IntrospectionSupport
IntSequenceGenerator
IOExceptionSupport
IOHelper
JavaBaseService	The BaseService provides helpers for dealing async service state.
JavaBaseService.STARTING

JMSExceptionSupport
JMXSupport
LockFile	Used to lock a File.
LongSequenceGenerator
LRUCache<K,V>	A Simple LRU Cache
MemoryPropertyEditor	Converts string values like "20 Mib", "1024kb", and "1g" to long values in bytes.
PriorityLinkedList<E extends LinkedNode<E>>
PriorityMap<E>
Scala2Java
Scala2Java.Logger
Scheduler
SchedulerTimerTask	A TimeTask for a Runnable object
ServiceStopper	A helper class used to stop a bunch of services, catching and logging any exceptions and then throwing the first exception when everything is stoped.
ServiceSupport	A helper class for working with services together with a useful base class for service implementations.
SslContext	A holder of SSL configuration.
StringSupport	Helper class to hold common text/string manipulation methods.
TimerHeap<V>
TreeMap<K,V>	A TreeMap that is lighter weight than the Sun implementation with implementations for upper/lower/floor/ceiling accessors.
TreeMap.TreeEntry<K,V>
URIEditor
