Interface Summary

Interface	Description
Action<E extends Exception>	An Runnable functional interface which can throw a checked Exception.
AsyncFunction<VIN,VOUT,E extends Exception>	An asynchronous Function which returns a result at some point in the future.
BiFunction<T,U,R,E extends Exception>	A BiFunction functional interface which can throw a checked Exception.
Consumer<T,E extends Exception>	A Consumer functional interface which can throw a checked Exception.
Factory<T>	A factory interface.
Function<VIN,VOUT,E extends Exception>	A synchronous function which returns a result immediately.
Indexed<T>	Interface of an object that can be indexed with a unique key.
Predicate<T,E extends Exception>	A Predicate functional interface which can thrown a checked Exception.
Supplier<T,E extends Exception>	A Supplier functional interface which can throw a checked Exception.

Class Summary

Class	Description
BlackAndWhitelistFilter	This class can be used for filtering string elements by using blacklists and/or whitelists.
Closeables	Common utility methods for Closeables.
CloseSilentlyAsyncFunction<VIN extends Closeable,VOUT,E extends Exception>	AsyncFunction that silently closes an input-parameter after a delegate-function's AsyncFunction.apply(Object) is completed.
CloseSilentlyFunction<VIN extends Closeable,VOUT,E extends Exception>	Function that silently closes an input-parameter after a delegate-function's Function.apply(Object) is invoked.
DirectoryWatcher	High-level interface to the WatchService API for detecting filesystem change events.
EnumValueOfHelper<E extends Enum<E>>	Provides a EnumValueOfHelper.valueOf(String) method as a replacement for the implicitly declared enum function valueOf(String), which has the advantage of not throwing exceptions when the name argument is null or cannot be found in the enum's values.
LambdaExceptionUtils	Utility methods for interacting with lambdas that throw exceptions.
LazyList<E>	A list with lazy initialization.
LazyMap<K,V>	A map with lazy initialization.
LazySupplier<T,E extends Exception>	A Supplier that lazily computes a value the first time it is accessed and then caches the result to return on subsequent requests.
ListDecorator<E>	Wraps another map.
Loader	Provides methods for dynamically loading classes.
MapDecorator<K,V>	Wraps another map.
NonExpiringCache<K,V>	Allows the Caching of an object.
Objects	Common utility methods for Objects.
Option<T>	A configuration option whose value can be stored in a set of Options.
Options	A set of options which can be used for customizing the behavior of HTTP clients and servers.
Pair<F,S>	Ordered pair of arbitrary objects.
PerItemEvictionStrategyCache<K,V>	PerItemEvictionStrategyCache is a thread-safe write-through cache.
RangeSet	Exposes a range of integer values as a set.
Reject	A input parameter-validating utility class using fluent invocation:
SignatureUtil	Utility class for signing and verifying signatures.
Streams	Utility methods for operating on IO streams.
Strings	Common utility methods for Strings.
Threads	Common utility methods for Threads.
Utils	Deprecated. Use Strings, Closeables, Objects or Threads instead.
