* Julian Dolby (dolby@us.ibm.com) |
44 |
|
* February 7, 2003 |
45 |
|
* |
46 |
|
* This code implements the GThreadFunctions interface for GLIB using |
47 |
|
* Java threading primitives. All of the locking and conditional variable |
48 |
|
* functionality required by GThreadFunctions is implemented using the |
49 |
|
* monitor and wait/notify functionality of Java objects. The thread- |
50 |
|
* local fucntionality uses the java.lang.ThreadLocal class. |
51 |
|
* |
52 |
|
* This code is designed to be portable in that it makes no assumptions |
53 |
|
* about the underlying VM beyond that it implements the JNI functionality |
54 |
|
* that this code uses. |
55 |
|
* |
56 |
|
* The one piece that does not really work is trylock for mutexes. The |
57 |
|
* Java locking model does not include such functionality, and I do not |
58 |
|
* see how to implement it without knowing something about how the VM |
59 |
|
* implements locking. |
60 |
|
* |
61 |
|
* NOTES: |
62 |
|
* |
63 |
|
* I have tested it only on JikesRVM---the CVS head as of early February |
64 |
|
* 2003. |
65 |
|
* |
66 |
|
* Currently, use of this code is governed by the configuration option |
67 |
|
* --enable-portable-native-sync |
