Interface Summary

Interface	Description
ConcurrentInitializer<T>	Definition of an interface for the thread-safe initialization of objects.

Class Summary

Class	Description
AtomicInitializer<T>	A specialized implementation of the ConcurrentInitializer interface based on an AtomicReference variable.
AtomicSafeInitializer<T>	A specialized ConcurrentInitializer implementation which is similar to AtomicInitializer, but ensures that the AtomicSafeInitializer.initialize() method is called only once.
BackgroundInitializer<T>	A class that allows complex initialization operations in a background task.
BasicThreadFactory	An implementation of the ThreadFactory interface that provides some configuration options for the threads it creates.
BasicThreadFactory.Builder	A builder class for creating instances of BasicThreadFactory.
CallableBackgroundInitializer<T>	A specialized BackgroundInitializer implementation that wraps a Callable object.
ConcurrentUtils	An utility class providing functionality related to the java.util.concurrent package.
ConstantInitializer<T>	A very simple implementation of the ConcurrentInitializer interface which always returns the same object.
LazyInitializer<T>	This class provides a generic implementation of the lazy initialization pattern.
MultiBackgroundInitializer	A specialized BackgroundInitializer implementation that can deal with multiple background initialization tasks.
MultiBackgroundInitializer.MultiBackgroundInitializerResults	A data class for storing the results of the background initialization performed by MultiBackgroundInitializer.
TimedSemaphore	A specialized semaphore implementation that provides a number of permits in a given time frame.

Exception Summary

Exception	Description
ConcurrentException	An exception class used for reporting error conditions related to accessing data of background tasks.
ConcurrentRuntimeException	An exception class used for reporting runtime error conditions related to accessing data of background tasks.

Package org.apache.commons.lang3.concurrent Description
