Package com.hazelcast.util

This package contains classes to support the inner workings of Hazelcast as well as some backports of newer Java features / data structures to support older Java versions in a clean and nice way.

Interface Summary

Interface	Description
ConstructorFunction<K,V>	See ConcurrencyUtil
FutureUtil.ExceptionHandler	Internally used interface to define behavior of the FutureUtil methods when exceptions arise
MemoryInfoAccessor	Used for providing runtime memory information of Java virtual machine.

Class Summary

Class	Description
AddressUtil	AddressUtil contains Address helper methods
AddressUtil.AddressHolder	Holds address
AddressUtil.AddressMatcher	http://docs.oracle.com/javase/1.5.0/docs/guide/net/ipv6_guide/index.html
Base64	This class provides encode/decode for RFC 2045 Base64 as defined by RFC 2045, N.
CacheConcurrentHashMap<K,V>	ConcurrentHashMap to extend iterator capability
Clock	Utility class to be able to simulate different time zones.
ConcurrencyUtil	Utility methods to getOrPutSynchronized and getOrPutIfAbsent in thread safe way from ConcurrentMap with a ConstructorFunction .
ConcurrentReferenceHashMap<K,V>	An advanced hash table supporting configurable garbage collection semantics of keys and values, optional referential-equality, full concurrency of retrievals, and adjustable expected concurrency for updates.
ConcurrentReferenceHashMap.SimpleEntry<K,V>
EmptyStatement	This class does nothing! It is useful if you e.g.
ExceptionUtil
FilteringClassLoader	This is used to separate Server and Client inside the same JVM on new standalone client unittests! NEVER EVER use this anywhere in production! :D
FutureUtil	This utility class contains convenience methods to work with multiple futures at the same time, e.g.
HashUtil
HealthMonitor	http://blog.scoutapp.com/articles/2009/07/31/understanding-load-averages http://docs.oracle.com/javase/7/docs/jre/api/management/extension/com/sun/management/OperatingSystemMXBean.html Health monitor periodically prints logs about related internal metrics under when hazelcast is under load.
IterableUtil	Utility functions for working with Iterable
JsonUtil	Utility class to deal with Json.
OperatingSystemMXBeanSupport	Support class for reading attributes from OperatingSystemMXBean.
PerformanceMonitor	The PerformanceMonitor is responsible for logging all kinds of performance related information.
QueryResultSet	Collection(Set) class for result of query operations
QuickMath	The class QuickMath contains methods to perform optimized mathematical operations.
RandomPicker	User: ahmetmircik Date: 10/7/13 Time: 12:27 PM
ResponseQueueFactory	Factory for creating response queues.
RuntimeMemoryInfoAccessor	Provides memory information using Runtime.
SampleableConcurrentHashMap<K,V>	ConcurrentHashMap to extend iterator capability.
ServiceLoader	Support class for loading Hazelcast services and hooks based on the Java ServiceLoader specification but changed in the fact of classloaders to test for given services to work in multi classloader environments like application or OSGi servers
SortedQueryResultSet	Collection class for results of query operations
SortingUtil	Utility class for generating Comparators to be used in sort methods specific to hazelcast classes.
StringUtil	Utility class for Strings.
ThreadUtil	Utility class to manipulate and query thread id
UuidUtil	Util class to generate random unique identifiers
ValidationUtil	A utility class for validating arguments and state.
VersionCheck	Checks version of hazelcast with central server.

Enum Summary

Enum	Description
ConcurrentReferenceHashMap.Option
ConcurrentReferenceHashMap.ReferenceType	An option specifying which Java reference type should be used to refer to a key and/or value.
HealthMonitorLevel	Health monitor can be configured with system properties "hazelcast.health.monitoring.level"
IterationType	To differentiate users selection on result collection on map-wide operations like values , keySet , query etc.

Exception Summary

Exception	Description
AddressUtil.InvalidAddressException	Thrown when given address is not valid.
