Class AbstractSignalHandler

java.lang.Object

net.sf.basedb.core.signal.AbstractSignalHandler

All Implemented Interfaces:

SignalHandler, Action

Direct Known Subclasses:

DelegatingSignalHandler, EnhancedThreadSignalHandler, ForwardingSignalHandler, ProgressReporterSignalHandler, ThreadSignalHandler

public abstract class AbstractSignalHandler
extends Object
implements SignalHandler

An abstract base class for signal handler implementations. This class will help an implementor of the SignalHandler interface to provide information about supported signals. The easiest way is to use the AbstractSignalHandler(Collection) constructor.
