Enclosing class:

AbstractLauncher<T extends Comparable<T>>

public abstract static class AbstractLauncher.ServiceState<T extends Comparable<T>>
extends Object

The ServiceState is an immutable type representing the state of the specified Locator at any given moment in time. The ServiceState associates the Locator with it's state at the exact moment an instance of this class is constructed.
