| 27 /** <P> This is a tag interface (similar to Cloneable) which indicates | |
| 28 that the contained address is "special" and is updated under the | |
| 29 hood by the VM. The purpose is to support implementation of | |
| 30 reflection on the current VM with these interfaces; if the Java | |
| 31 code implementing parts of the VM requires proxies for objects in | |
| 32 the heap, it must be the case that those proxies are updated if GC | |
| 33 occurs. This is the level at which this updating is handled. The | |
| 34 VM (and specifically the GC code) must have intimate knowledge of | |
| 35 the VM-specific implementation of this interface. </P> | |
| 36 | |
| 37 <P> Note that in the case of debugging a remote VM, it is not | |
| 38 workable to handle the automatic updating of these handles. | |
| 39 If the debugger allows the VM to resume running, it will have to | |
| 40 look up once again any object references via the path they were | |
| 41 found (i.e., the activation on the stack as the root, etc.) </P> | |
