Uses of ConcurrentInitializer in org.apache.commons.lang3.concurrent

Classes in org.apache.commons.lang3.concurrent that implement ConcurrentInitializer

Modifier and Type	Class	Description
class	AbstractConcurrentInitializer<T,E extends Exception>	Abstracts and defines operations for ConcurrentInitializer implementations.
class	AtomicInitializer<T>	A specialized implementation of the ConcurrentInitializer interface based on an AtomicReference variable.
class	AtomicSafeInitializer<T>	A specialized ConcurrentInitializer implementation which is similar to AtomicInitializer, but ensures that the AbstractConcurrentInitializer.initialize() method is called only once.
class	BackgroundInitializer<T>	A class that allows complex initialization operations in a background task.
class	CallableBackgroundInitializer<T>	A specialized BackgroundInitializer implementation that wraps a Callable object.
class	ConstantInitializer<T>	A very simple implementation of the ConcurrentInitializer interface which always returns the same object.
class	LazyInitializer<T>	This class provides a generic implementation of the lazy initialization pattern.
class	MultiBackgroundInitializer	A specialized BackgroundInitializer implementation that can deal with multiple background initialization tasks.

Methods in org.apache.commons.lang3.concurrent with parameters of type ConcurrentInitializer

Modifier and Type	Method	Description
static <K, V> V	ConcurrentUtils.createIfAbsent(ConcurrentMap<K,V> map, K key, ConcurrentInitializer<V> init)	Checks if a concurrent map contains a key and creates a corresponding value if not.
static <K, V> V	ConcurrentUtils.createIfAbsentUnchecked(ConcurrentMap<K,V> map, K key, ConcurrentInitializer<V> init)	Checks if a concurrent map contains a key and creates a corresponding value if not, suppressing checked exceptions.
static <T> T	ConcurrentUtils.initialize(ConcurrentInitializer<T> initializer)	Invokes the specified ConcurrentInitializer and returns the object produced by the initializer.
static <T> T	ConcurrentUtils.initializeUnchecked(ConcurrentInitializer<T> initializer)	Invokes the specified ConcurrentInitializer and transforms occurring exceptions to runtime exceptions.
