| // The system dictionary stores all loaded classes and maps: |
| // |
| // [class name,class loader] -> class i.e. [symbolOop,oop] -> klassOop |
| // |
| // Classes are loaded lazily. The default VM class loader is |
| // represented as NULL. |
| |
| // The underlying data structure is an open hash table with a fixed number |
| // of buckets. During loading the loader object is locked, (for the VM loader |
| // a private lock object is used). Class loading can thus be done concurrently, |
| // but only by different loaders. |
| // |
| // During loading a placeholder (name, loader) is temporarily placed in |
| // a side data structure, and is used to detect ClassCircularityErrors |
| // and to perform verification during GC. A GC can occur in the midst |
| // of class loading, as we call out to Java, have to take locks, etc. |
| // |
| // When class loading is finished, a new entry is added to the system |
| // dictionary and the place holder is removed. Note that the protection |
| // domain field of the system dictionary has not yet been filled in when |
| // the "real" system dictionary entry is created. |
| // |
| // Clients of this class who are interested in finding if a class has |
| // been completely loaded -- not classes in the process of being loaded -- |
| // can read the SystemDictionary unlocked. This is safe because |
| // - entries are only deleted at safepoints |
| // - readers cannot come to a safepoint while actively examining |
| // an entry (an entry cannot be deleted from under a reader) |
| // - entries must be fully formed before they are available to concurrent |
| // readers (we must ensure write ordering) |
| // |
| // Note that placeholders are deleted at any time, as they are removed |
| // when a class is completely loaded. Therefore, readers as well as writers |
| // of placeholders must hold the SystemDictionary_lock. |
