/** <P> DebuggerBase is a recommended base class for debugger |
|
28 |
implementations. It can use a PageCache to cache data from the |
|
29 |
target process. Note that this class would not be suitable if the |
|
30 |
system were used to reflect upon itself; it would never be safe to |
|
31 |
store the value in an OopHandle in anything but an OopHandle. |
|
32 |
However, it provides a fair amount of code sharing to the current |
|
33 |
dbx and win32 implementations. </P> |
|
34 |
||
35 |
<P> NOTE that much of the code sharing is achieved by having this |
|
36 |
class implement many of the methods in the Win32Debugger and |
|
37 |
DbxDebugger interfaces. </P> */ |
