| michael@0 | 38 | * Using nsIContent** instead of nsIContent* is the parser deals with DOM |
| michael@0 | 39 | * nodes in a way that works off the main thread. Non-main-thread code |
| michael@0 | 40 | * can't refcount or otherwise touch nsIContent objects in any way. |
| michael@0 | 41 | * Yet, the off-the-main-thread code needs to have a way to hold onto a |
| michael@0 | 42 | * particular node and repeatedly operate on the same node. |
| michael@0 | 43 | * |
| michael@0 | 44 | * The way this works is that the off-the-main-thread code has an |
| michael@0 | 45 | * nsIContent** for each DOM node and a given nsIContent** is only ever |
| michael@0 | 46 | * actually dereferenced into an actual nsIContent* on the main thread. |
| michael@0 | 47 | * When the off-the-main-thread code requests a new node, it gets an |
| michael@0 | 48 | * nsIContent** immediately and a tree op is enqueued for later allocating |
| michael@0 | 49 | * an actual nsIContent object and writing a pointer to it into the memory |
| michael@0 | 50 | * location pointed to by the nsIContent**. |
| michael@0 | 51 | * |
| michael@0 | 52 | * Since tree ops are in a queue, the node creating tree op will always |
| michael@0 | 53 | * run before tree ops that try to further operate on the node that the |
| michael@0 | 54 | * nsIContent** is a handle to. |
| michael@0 | 55 | * |
| michael@0 | 56 | * On-the-main-thread parts of the parser use nsIContent* instead of |
| michael@0 | 57 | * nsIContent**. Since both cases share the same parser core, the parser |
| michael@0 | 58 | * core casts both to nsIContentHandle*. |
