All Implemented Interfaces:

java.io.Serializable

Enclosing class:

AbruptCompletion

public static final class AbruptCompletion.Nonlocal
extends java.lang.Error

This class 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. It extends Error so that it is not catched and discarded by well-behaved Java programs (which would lead to improper behaviour of the non-local transfer mechanism).
