A Java library with data structures developed for various projects. Many of the structures have to do with concurrency.
Classes
- AtomicStack - a thread-safe wait-free stack implementation.
- BlockableQueue - a queue implementation which can toggle between blocking and non-blocking.
- ConcurrentSet - a thread-safe set of objects.
- Files - file copying functionality.
- Gate - a lock that stops all waiting threads until one of the threads open the gate. An item is held behind the gate and all blocking threads receive that object upon opening.
- Ref - an interface that merely holds some value (get/set methods).
- LockRef - Ref implementation that is an efficient reentrant read-write lock. Readers don't block each other, but a write will.
- NonNullRef - Ref implementation that blocks until a non-null value is set
- Notifier - A dynamic proxy class used for notifying a list of listeners. Objects of the same type are added, when the proxy().METHOD is called, it calls METHOD on all objects added to the notifier.
- Release - A utility for unblocking blocking calls.
- Signal - Provides a way for several threads to send signals between each other.
- Sleepable -Any entity which blocks its thread for some period of time or until some event occurs and can be nicely awoken.
- State - A thread-safe state machine used for keeping track of the state of some object, waiting for a state to occur, and changing states.
- EnumState - Similar to State, but holds a single state (enum) opposed to multiple states

Example
/** Snippet with the utilities that ARE NOT related to concurrency. See JavaDocs to
view snippets of concurrent classes. **/
// Copy one file/dir to another file/dir.
Files.copy(new File("src_dir"), new File("dst_dir"));
// A listener to the bar event
public interface Foo {
public void onBar();
}
// Create a notifier to invoke all Foos with one invocation.
Notifier<Foo> notifier = Notifier.create(Foo.class);
notifier.add(new Foo());
notifier.add(new Foo());
// Invoke onBar to all Foo added to notifier
notifier.proxy().onBar();Builds
