31 /** <P> This interface describes the methods which are used in a
32 remote debugging scenario. It is only necessary because RMI
33 requires that all such methods throw RemoteException, which is a
34 checked (i.e., not a Runtime) exception. Since we already have a
35 suitable runtime exception (DebuggerException) present in the
36 signatures for all of the debugger-related methods, we would like
37 to repurpose this to wrap RemoteExceptions. This is done by
38 wrapping the actual remote debugger object
39 </P>
40
41 <P> NOTE that this interface currently assumes that the debugger
42 on the remote machine has already been attached to the target
43 process or has opened the desired core file. This implies that the
44 machine hosting the user interface can not effect
45 attaching/detaching. Currently this restriction has been enforced
46 to make the user interface less confusing, but there will also be
47 security concerns with allowing clients to attach to arbitrary
48 remote processes. </P>
