Interface Summary

Interface	Description
ConcurrentSet<E>	A ConcurrentSet
ExecutorFactory	A ExecutorFactory
HornetQUtilBundle
HornetQUtilLogger
IDGenerator	Generator of record IDs for the journals.
LinkedList<E>	A LinkedList
LinkedListIterator<E>	A LinkedListIterator This iterator allows the last element to be repeated in the next call to hasNext or next
MemorySize.ObjectFactory
PriorityLinkedList<T>	A type of linked list which maintains items according to a priority and allows adding and removing of elements at both ends, and peeking
SensitiveDataCodec<T>	A SensitiveDataCodec This interface is used for implementing a value decoder.
SoftValueHashMap.ValueCache
TokenBucketLimiter	This class can throttle to a specific rate, using an algorithm based on the Token Bucket metaphor.

Class Summary

Class	Description
Base64	Encodes and decodes to and from Base64 notation.
Base64.InputStream	A Base64.InputStream will read data from another java.io.InputStream, given in the constructor, and encode/decode to/from Base64 notation on the fly.
Base64.OutputStream	A Base64.OutputStream will write data to another java.io.OutputStream, given in the constructor, and encode/decode to/from Base64 notation on the fly.
BufferHelper	Helper methods to read and write from HornetQBuffer.
ByteUtil
ClassloadingUtil	This class will be used to perform generic class-loader operations, such as load a class first using TCCL, and then the classLoader used by HornetQ (ClassloadingUtil.getClass().getClassLoader()).
ConcurrentHashSet<E>	A ConcurrentHashSet.
ConfigurationHelper	A ConfigurationHelper
DataConstants	A DataConstants
DefaultSensitiveStringCodec	A DefaultSensitiveDataCodec The default implementation of SensitiveDataCodec.
DeflaterReader	A DeflaterReader The reader takes an inputstream and compress it.
FutureLatch	A Future
HornetQBufferInputStream	Used to send large messages
HornetQThreadFactory	A HornetQThreadFactory
InflaterReader	An InflaterReader It takes an compressed input stream and decompressed it as it is being read.
InflaterWriter	A InflaterWriter This class takes an OutputStream.
JNDIUtil
LinkedListImpl<E>	A linked list implementation which allows multiple iterators to exist at the same time on the queue, and which see any elements added or removed from the queue either directly or via iterators.
MemorySize	A MemorySize
ObjectInputStreamWithClassLoader
OrderedExecutorFactory	A factory for producing executors that run all tasks in order, which delegate to a single common executor instance.
PasswordMaskingUtil	A PasswordMarkingUtil
PriorityLinkedListImpl<T>	A priority linked list implementation It implements this by maintaining an individual LinkedBlockingDeque for each priority level.
Random	A Random
ReusableLatch	This class will use the framework provided to by AbstractQueuedSynchronizer.
SecurityFormatter
SimpleIDGenerator	A SimpleIDGenerator
SizeFormatterUtil	A SizeFormatterUtil
SoftValueHashMap<K,V extends SoftValueHashMap.ValueCache>	A SoftValueHashMap
TimeAndCounterIDGenerator	A TimeAndCounterIDGenerator
TokenBucketLimiterImpl	A TokenBucketLimiterImpl
TypedProperties	Property Value Conversion.
UTF8Util	A UTF8Util This class will write UTFs directly to the ByteOutput (through the MessageBuffer interface)
UUID	UUID represents Universally Unique Identifiers (aka Global UID in Windows world).
UUIDGenerator
UUIDTimer	UUIDTimer produces the time stamps required for time-based UUIDs.
VersionLoader	This loads the version info in from a version.properties file.
XidCodecSupport
XMLConfigurationUtil	A XMLConfigurationUtil
XMLUtil
