| 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> | |
