Package org.apache.activemq.util

Interface Summary

Callback	A simple callback object used by the org.apache.activemq.util.TransactionTemplate and org.apache.activemq.util.ExceptionTemplate objects to provide automatic transactional or exception handling blocks.
FactoryFinder.ObjectFactory	The strategy that the FactoryFinder uses to find load and instantiate Objects can be changed out by calling the FactoryFinder.setObjectFactory(org.apache.activemq.util.FactoryFinder.ObjectFactory) method with a custom implementation of ObjectFactory.
ServiceListener	A listener for service start, stop events
Suspendable	Interface implemented by services that can be suspended and resumed.
TypeConversionSupport.Converter

Class Summary

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
ByteArrayInputStream	Very similar to the java.io.ByteArrayInputStream but this version is not thread safe.
ByteArrayOutputStream	Very similar to the java.io.ByteArrayOutputStream but this version is not thread safe and the resulting data is returned in a ByteSequence to avoid an extra byte[] allocation.
ByteSequence
ByteSequenceData	Used to write and read primitives to and from a ByteSequence.
ClassLoadingAwareObjectInputStream
DataByteArrayInputStream	Optimized ByteArrayInputStream that can be used more than once
DataByteArrayOutputStream	Optimized ByteArrayOutputStream
FactoryFinder
FactoryFinder.StandaloneObjectFactory	The default implementation of Object factory which works well in standalone applications.
IdGenerator	Generator for Globally unique Strings.
IndentPrinter	A helper class for printing indented text
InetAddressUtil
IntrospectionSupport
IntSequenceGenerator
IOExceptionSupport
JMSExceptionSupport
LongSequenceGenerator
LRUCache<K,V>	A Simple LRU Cache
MapHelper	A bunch of utility methods for working with maps
MarshallingSupport	The fixed version of the UTF8 encoding function.
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.
StopWatch	A very simple stop watch.
StringArrayConverter	Class for converting to/from String[] to be used instead of a PropertyEditor which otherwise causes memory leaks as the JDK PropertyEditorManager is a static class and has strong references to classes, causing problems in hot-deployment environments.
StringToListOfActiveMQDestinationConverter	Special converter for String -> List to be used instead of a PropertyEditor which otherwise causes memory leaks as the JDK PropertyEditorManager is a static class and has strong references to classes, causing problems in hot-deployment environments.
ThreadPoolUtils	Utility methods for working with thread pools ExecutorService.
TimeUtils	Time utils.
TypeConversionSupport	Type conversion support for ActiveMQ.
URISupport	Utility class that provides methods for parsing URI's This class can be used to split composite URI's into their component parts and is used to extract any URI options from each URI in order to set specific properties on Beans.
URISupport.CompositeData	A composite URI can be split into one or more CompositeData object which each represent the individual URIs that comprise the composite one.
