public interface Callback
All callback definitions must derive from this interface. Any
derived interfaces must define a single public method (which may not be named
"hashCode", "equals", or "toString"), or one public method named "callback".
You are responsible for deregistering your callback (if necessary)
in its Object.finalize()
method. If native code attempts to call
a callback which has been GC'd, you will likely crash the VM. If
there is no method to deregister the callback (e.g. atexit
in the C library), you must ensure that you always keep a live reference
to the callback object.
A callback should generally never throw an exception, since it doesn't necessarily have an encompassing Java environment to catch it. Any exceptions thrown will be passed to the default callback exception handler.
