Move the private and internal APIs of QDom to new files
qdom.cpp is too big, move the private classes and internal classes to new files to make the maintenance and reviews for the upcoming changes easier. Task-number: QTBUG-76178 Change-Id: Ibe83bf9104e000d405a07653f4278083e2da648e Reviewed-by: Kai Koehne <kai.koehne@qt.io>

Counter for the QDomNodeListPrivate timestamps.
|
||||
|
||||
This is a cache optimization, that might in some cases be effective. The
|
||||
dilemma is that QDomNode::childNodes() returns a list, but the
|
||||
implementation stores the children in a linked list. Hence, in order to
|
||||
get the children out through childNodes(), a list must be populated each
|
||||
time, which is O(N).
|
||||
|
||||
DOM has the requirement of node references being live, see DOM Core
|
||||
Level 3, 1.1.1 The DOM Structure Model, which means that changes to the
|
||||
underlying documents must be reflected in node lists.
|
||||
|
||||
This mechanism, nodeListTime, is a caching optimization that reduces the
|
||||
amount of times the node list is rebuilt, by only doing so when the
|
||||
document actually changes. However, a change to anywhere in any document
|
||||
invalidate all lists, since no dependency tracking is done.
|
||||
|
||||
It functions by that all modifying functions(insertBefore() and so on)
|
||||
increment the count; each QDomNodeListPrivate copies nodeListTime on
|
||||
construction, and compares its own value to nodeListTime in order to
|
||||
determine whether it needs to rebuild.
|
||||
|
||||
This is reentrant. The nodeListTime may overflow, but that's ok since we
|
||||
check for equalness, not whether nodeListTime is smaller than the list's
|
||||
stored timestamp.

Counter for the QDomNodeListPrivate timestamps.
|

|

This is a cache optimization, that might in some cases be effective. The
|
||||
dilemma is that QDomNode::childNodes() returns a list, but the
|
||||
implementation stores the children in a linked list. Hence, in order to
|
||||
get the children out through childNodes(), a list must be populated each
|
||||
time, which is O(N).
|
||||
|
||||
DOM has the requirement of node references being live, see DOM Core
|
||||
Level 3, 1.1.1 The DOM Structure Model, which means that changes to the
|
||||
underlying documents must be reflected in node lists.
|
||||
|
||||
This mechanism, nodeListTime, is a caching optimization that reduces the
|
||||
amount of times the node list is rebuilt, by only doing so when the
|
||||
document actually changes. However, a change to anywhere in any document
|
||||
invalidate all lists, since no dependency tracking is done.
|
||||
|
||||
It functions by that all modifying functions(insertBefore() and so on)
|
||||
increment the count; each QDomNodeListPrivate copies nodeListTime on
|
||||
construction, and compares its own value to nodeListTime in order to
|
||||
determine whether it needs to rebuild.
|
||||
|
||||
This is reentrant. The nodeListTime may overflow, but that's ok since we
|
||||
check for equalness, not whether nodeListTime is smaller than the list's
|
||||
stored timestamp.
