Interface Catcher<S>

All Known Implementing Classes:

Catcher0, CatcherL, CatcherP, PropertyChangeListenerR.DispatchCatcher, PropertyChangeListenerR.DispatchCatcherN

public interface Catcher<S>

A catcher of errors and exceptions.

Subtype implementers note: if adding catch methods, bear in mind that dispatch is decided according to formal parameter type at compile time; not actual type at runtime -- unlike catch statement parameters. Best to use a new, distinct name for each new method; rather than overload the ones defined here.
