Interface Catcher<S>

All Known Implementing Classes:

Catcher00, Catcher0R, CatcherL, CatcherP

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.

catchException

void catchException(S source,
                  Exception x)

Handles an exception.

Parameters:
