Examples of co.paralleluniverse.fibers.Fiber

co.paralleluniverse.fibers.Fiber
A lightweight thread.
There are two ways to create a new fiber: either subclass the {@code Fiber} class and override the {@code run} method,or pass the code to be executed in the fiber as the {@code target} parameter to the constructor. All in all, the Fiber APIresembles the {@link Thread} class in many ways.
A fiber runs inside a ForkJoinPool.
A Fiber can be serialized if it's not running and all involved classes and data types are also {@link Serializable}.
A new Fiber occupies under 400 bytes of memory (when using the default stack size, and compressed OOPs are turned on, as they are by default). @param < V> The type of the fiber's result value. Should be set to {@link Void} if no value is to be returned by the fiber. @author pron
