The purpose is to support implementation of + reflection on the current VM with these interfaces; if the Java + code implementing parts of the VM requires proxies for objects in + the heap, it must be the case that those proxies are updated if GC + occurs. This is the level at which this updating is handled. The + VM (and specifically the GC code) must have intimate knowledge of + the VM-specific implementation of this interface. </P> + + <P> Note that in the case of debugging a remote VM, it is not + workable to handle the automatic updating of these handles. + If the debugger allows the VM to resume running, it will have to + look up once again any object references via the path they were + found (i.e., the activation on the stack as the root, etc.) </P> +*/ + +public interface OopHandle extends Address { +}
