seda.sandStorm.internal.SignalMgr
- All Implemented Interfaces:
- SignalMgrIF
class SignalMgr
- extends java.lang.Object
- implements SignalMgrIF
The SignalMgr is an implementation of SignalMgrIF. It allows stages
to register to receive certain signals and delivers those signals once

SignalMgr
SignalMgr()
register
public void register(SignalIF signalType,
SinkIF sink)
- Register for the given signal type. When the signal is triggered,
an object of the given type (although not necessarily the same
object instance) will be delivered to the given SinkIF.
- Specified by:
register
in interface SignalMgrIF
deregister
public void deregister(SignalIF signalType,
SinkIF sink)
- Deregister for the given signal type.
- Specified by:
deregister
in interface SignalMgrIF
trigger
public void trigger(SignalIF signal)
- Send the given signal to all registered sinks. Uses enqueue_lossy
on each sink, so if a sink rejects the signal this method will
continue regardless. Package access only.
XXX MDW: Really should register sinks with the chain of superclasses
for each signal as well, so that triggering a superclass of a given
signal will also reach those sinks registered for the subclass.
