Mandatory Set Members
|
|
|
|
=====================
|
|
|
|
|
|
|
|
- A set member can be marked as "mandatory," meaning that a member of that name
|
|
|
|
must always be present in a set.
|
|
|
|
|
|
|
|
- The above definition implies that calling replaceByName on a mandatory set
|
|
|
|
member is OK.
|
|
|
|
|
|
|
|
- The XCU format can contain oor:mandatory attributes on nodes. (The XCS format
|
|
|
|
does not support them. In the registrymodifications file, oor:mandatory
|
|
|
|
attributes should never be needed, as being mandatory cannot be controlled via
|
|
|
|
the UNO API.) The XCU reading code only evaluates the oor:mandatory attribute
|
|
|
|
for set members, and ignores it everywhere else.
|
|
|
|
|
|
|
|
- Only true sets support mandatory members. A localized property for the "*"
|
|
|
|
locale, though acting much like a set, does not support mandatory members.
|
|
|
|
|
|
|
|
- The OpenOffice.org Registry Format document claims that group extension
|
|
|
|
properties are implicitly mandatory, but at least the new configmgr code does
|
|
|
|
not treat them like that (i.e., they can be removed again).
|
|
|
|
|
|
|
|
- For simplicity, setMandatory/getMandatory are available as virtual functions
|
|
|
|
at the base Node, even though they can only make sense for GroupNodes and
|
|
|
|
SetNodes that are set members. The default getMandatory implementation returns
|
|
|
|
NO_LAYER, meaning oor:mandatory is not set to true in any layer. (Returning
|
|
|
|
NO_LAYER simplifies the code, e.g., removeByName does not have to check whether
|
|
|
|
getMandatory is called on a member of a true set to decide whether to forbid
|
|
|
|
removal.)
|
|
|
|
|
|
|
|
- When committing changes (made through the UNO API), the "mandatory" status of
|
|
|
|
inserted nodes must be updated (in case the insert is due to a replaceByName, or
|
|
|
|
the "mandatory" flag was added by a concurrent modification of a lower layer).
|
|
|
|
Also, for to-be-removed nodes, removal is ignored for (newly; due to concurrent
|
|
|
|
modification of a lower layer) mandatory nodes (but still recorded in
|
|
|
|
registrymodifications, so may take effect once the lower layer addition is
|
|
|
|
removed again---whether or not that is a good idea).

XcuParser Modification Recording
|
|
|
|
================================
|
|
|
|
|
|
|
|
- XcuParser records modifications when reading user layer data
|
|
|
|
(valueParser_.getLayer() == Data::NO_LAYER).
|
|
|
|
|
|
|
|
- oor:finalized and oor:mandatory attributes cannot be set via the UNO API, so
|
|
|
|
it is assumed that user layer data does not contain them (for one, they are not
|
|
|
|
written by writeModFile; for another, the logic to record modifications expects
|
|
|
|
a locprop(modify,fuse) to be followed by one or more value(fuse,remove), which
|
|
|
|
would not necessarily be true if the locprop were only present in the user layer
|
|
|
|
data to flag it as finalized).
|
|
|
|
|
|
|
|
- The logic to record modifications considers the top of the XML element stack.
|
|
|
|
In the following list of all possible cases, items marked with an asterisk are
|
|
|
|
recorded:
|
|
|
|
... group(modify,fuse) - group(modify,fuse) - ...
|
|
|
|
... group(modify,fuse) - set(modify,fuse) - ...
|
|
|
|
... group(modify,fuse) - *prop(modify,fuse,replace) - value(fuse)
|
|
|
|
... group(modify,fuse) - *prop(remove)
|
|
|
|
... group(modify,fuse) - locprop(modify,fuse) - *value(fuse)
|
|
|
|
... group(modify,fuse) - locprop(modify,fuse) - *value(remove)
|
|
|
|
... group(modify,fuse) - *locprop(replace) ...
|
|
|
|
... set(modify,fuse,replace) - group(modify/fuse) - ...
|
|
|
|
... set(modify,fuse,replace) - *group(replace/fuse) - ...
|
|
|
|
... set(modify,fuse,replace) - *group(remove)
|
|
|
|
... set(modify,fuse,replace) - set(modify/fuse) - ...
|
|
|
|
... set(modify,fuse,replace) - *set(replace/fuse) - ...
|
|
|
|
... set(modify,fuse,replace) - *set(remove)
|
|
|
|
Legend: "...": zero or more further items
|
|
|
|
"- ...": one or more further items
|
|
|
|
"modify,fuse" etc.: any of those operations
|
|
|
|
"modify/fuse": a modify or a fuse on an existing member
|
|
|
|
"replace/fuse": a replace or a fuse on a non-existing member
|
