public abstract class AbruptCompletion
extends java.lang.RuntimeException

Base class for abrupt completions. An abrupt completion is one of the following:

• A AbruptCompletion.Break with a label.
• A AbruptCompletion.Return with a value.
• A AbruptCompletion.Throw with a throwable as its cause.

Abrupt completions are RuntimeExceptions that have to be caught at suitable locations.

The class AbruptCompletion.Nonlocal wraps an abrupt completion that has to be transferred (non-locally) to a statically containing routine invocation before Java's catching mechanism comes into play.
