Package org.apache.activemq.artemis.utils

Interface Summary

Interface	Description
ConcurrentSet<E>	A ConcurrentSet
ExecutorFactory
FactoryFinder.ObjectFactory	The strategy that the FactoryFinder uses to find load and instantiate Objects can be changed out by calling the setObjectFactory method with a custom implementation of ObjectFactory.
HashProcessor	Used to process Hash text for passwords
IDGenerator	Generator of record IDs for the journals.
LinkedList<E>
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
ReferenceCounter
SensitiveDataCodec<T>	A SensitiveDataCodec This interface is used for implementing a value decoder.
SimpleFuture<V>
SoftValueHashMap.ValueCache
TimeUtils.CheckMethod
TokenBucketLimiter	This class can throttle to a specific rate, using an algorithm based on the Token Bucket metaphor.

Class Summary

Class	Description
ActiveMQBufferInputStream	Used to send large messages
ActiveMQThreadFactory
ActiveMQThreadPoolExecutor
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 ActiveMQBuffer.
ByteUtil
CertificateUtil
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 ActiveMQ Artemis (ClassloadingUtil.getClass().getClassLoader()).
ConcurrentHashSet<E>	A ConcurrentHashSet.
ConcurrentUtil
ConfigurationHelper
ConfirmationWindowWarning	TODO: get rid of this
DataConstants
DefaultSensitiveStringCodec	A DefaultSensitiveDataCodec The default implementation of SensitiveDataCodec.
DeflaterReader	A DeflaterReader The reader takes an inputstream and compress it.
Env	Utility that detects various properties specific to the current runtime environment, such as JVM bitness and OS type.
FactoryFinder
FactoryFinder.StandaloneObjectFactory	The default implementation of Object factory which works well in standalone applications.
FileUtil
FutureLatch
InflaterReader	InflaterReader It takes a compressed input stream and decompressed it as it is being read.
InflaterWriter	InflaterWriter
IPV6Util
JNDIUtil
JsonLoader	This is to make sure we use the proper classLoader to load JSon libraries.
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
NoHashProcessor	A hash processor that just does plain text comparison
ObjectInputStreamWithClassLoader
OrderedExecutorFactory	A factory for producing executors that run all tasks in order, which delegate to a single common executor instance.
OrderedExecutorFactory.OrderedExecutor	An executor that always runs all tasks in order, using a delegate executor to run the tasks.
PasswordMaskingUtil
PendingTask	This is similar to a Runnable, except that we throw exceptions.
PriorityLinkedListImpl<T>	A priority linked list implementation
RandomUtil
ReferenceCounterUtil
ReusableLatch	This class will use the framework provided to by AbstractQueuedSynchronizer.
SecureHashProcessor	Hash function
SecurityFormatter
SelectorTranslator	This class converts a JMS selector expression into an ActiveMQ Artemis core filter expression.
SimpleFutureImpl<V>
SimpleIDGenerator
SizeFormatterUtil
SoftValueHashMap<K,V extends SoftValueHashMap.ValueCache>
StringEscapeUtils
StringUtil
TimeAndCounterIDGenerator	A TimeAndCounterIDGenerator
TimeUtils	Time utils.
TokenBucketLimiterImpl
TypedProperties	Property Value Conversion.
UTF8Util	A UTF8Util This class will write UTFs directly to the ByteOutput (through the MessageBuffer interface)
UTF8Util.StringUtilBuffer
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
XMLUtil
