* The Document interface represents the entire HTML or XML document. |
|
63 |
* Conceptually, it is the root of the document tree, and provides the |
|
64 |
* primary access to the document's data. |
|
65 |
* <P> |
|
66 |
* Since elements, text nodes, comments, processing instructions, |
|
67 |
* etc. cannot exist outside the context of a Document, the Document |
|
68 |
* interface also contains the factory methods needed to create these |
|
69 |
* objects. The Node objects created have a ownerDocument attribute |
|
70 |
* which associates them with the Document within whose context they |
|
71 |
* were created. |
|
72 |
* <p> |
|
73 |
* The CoreDocumentImpl class only implements the DOM Core. Additional modules |
|
74 |
* are supported by the more complete DocumentImpl subclass. |
|
75 |
* <p> |
|
76 |
* <b>Note:</b> When any node in the document is serialized, the |
|
77 |
* entire document is serialized along with it. |

* Number of alterations made to this document since its creation. |
|
152 |
* Serves as a "dirty bit" so that live objects such as NodeList can |
|
153 |
* recognize when an alteration has been made and discard its cached |
|
154 |
* state information. |
|
155 |
* <p> |
|
156 |
* Any method that alters the tree structure MUST cause or be |
|
157 |
* accompanied by a call to changed(), to inform it that any outstanding |
|
158 |
* NodeLists may have to be updated. |
|
159 |
* <p> |
|
160 |
* (Required because NodeList is simultaneously "live" and integer- |
|
161 |
* indexed -- a bad decision in the DOM's design.) |
|
162 |
* <p> |
|
163 |
* Note that changes which do not affect the tree's structure -- changing |
|
164 |
* the node's name, for example -- do _not_ have to call changed(). |
|
165 |
* <p> |
|
166 |
* Alternative implementation would be to use a cryptographic |
|
167 |
* Digest value rather than a count. This would have the advantage that |
|
168 |
* "harmless" changes (those producing equal() trees) would not force |
|
169 |
* NodeList to resynchronize. Disadvantage is that it's slightly more prone |
|
170 |
* to "false negatives", though that's the difference between "wildly |
|
171 |
* unlikely" and "absurdly unlikely". IF we start maintaining digests, |
|
172 |
* we should consider taking advantage of them. |
|
173 |
* |
|
174 |
* Note: This used to be done a node basis, so that we knew what |
|
175 |
* subtree changed. But since only DeepNodeList really use this today, |
|
176 |
* the gain appears to be really small compared to the cost of having |
|
177 |
* an int on every (parent) node plus having to walk up the tree all the |
|
178 |
* way to the root to mark the branch as changed everytime a node is |
|
179 |
* changed. |
|
180 |
* So we now have a single counter global to the document. It means that |
|
181 |
* some objects may flush their cache more often than necessary, but this |
|
182 |
* makes nodes smaller and only the document needs to be marked as changed. |
