Interface Callback

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.

public Collection FORBIDDEN_NAMES
These method names may not be used for a callback method.
public String METHOD_NAME
You must this method name if your callback interface has multiple
public methods. Typically a callback will have only one such
method, in which case any method name may be used, with the exception
of those in
FORBIDDEN_NAMES.
