public InvocationEvent(Object source, Runnable runnable)
InvocationEvent
with the specified
source which will execute the runnable's run
method when dispatched.
This is a convenience constructor. An invocation of the form
InvocationEvent(source, runnable)
behaves in exactly the same way as the invocation of
InvocationEvent
(source, runnable, null, false).
This method throws an IllegalArgumentException
if source
is null
.

public InvocationEvent(Object source, Runnable runnable, Object notifier, boolean catchThrowables)
InvocationEvent
with the specified
source which will execute the runnable's run
method when dispatched. If notifier is non-null
,
notifyAll()
will be called on it
immediately after run
returns.
