| 27 /** <P> This interface abstracts raw access to operating system-level | |
| 28 threads. In a debugging environment these methods map to, for | |
| 29 example, thread_db calls on Solaris (see /usr/include/thread_db.h) | |
| 30 or the Win32 debugging API calls. In a runtime environment these | |
| 31 might map directly to pthread calls. </P> | |
| 32 | |
| 33 <P> Implementors of this interface must provide equals() and | |
| 34 hashCode() methods which work properly regardless of how the | |
| 35 ThreadProxy is obtained, in particular either through {@link | |
| 36 sun.jvm.hotspot.debugger.ThreadAccess} or the thread list provided | |
| 37 by {@link sun.jvm.hotspot.debugger.cdbg.CDebugger}. This allows | |
| 38 matching up of the OS's notion of the thread list of the target | |
| 39 process with any user-level lists that may be present (i.e., the | |
| 40 JavaThread list in the HotSpot VM). </P> | |
| 41 | |
| 42 <P> Implementors of this interface should also provide a | |
| 43 toString() which converts the ThreadProxy to a value easily | |
| 44 recognizable in the platform's debugger. (For example, on Solaris, | |
| 45 "t@<id>".) </P> | |
| 46 | |
| 47 <P> FIXME: had to be renamed from "Thread" to avoid numerous | |
| 48 clashes with java.lang.Thread -- would be nice to pick a more | |
| 49 consistent name with the rest of the system. </P> */ | |
