- can run doxygen with an alternative Doxyfile, which is useful
when verifying generated content for particular classes.
Eg,
PATH/doc/Allwmake -dir $PWD
- Previously matched name against the object->name() method
but saved with iter.key(). Now use iter.key() more consistently.
STYLE: consistent parameter names (doxygen)
- std::initializer_list has its own size() method, so no need to use
std::distance.
STYLE/BUG: use separate iterator de-reference and increment in List
- avoids unnecessary copying of iterators, and avoids any potentially
odd behaviour with the combination with incrementing.
ENH: support construct from iterator pair for DynamicList, SortableList
- inherit from std::iterator to obtain the full STL typedefs, meaning
that std::distance works and the following is now possible:
labelRange range(100, 1500);
scalarList list(range.begin(), range.end());
--
Note that this does not work (mismatched data-types):
scalarList list = identity(12345);
But this does, since the *iter promotes label to scalar:
labelList ident = identity(12345);
scalarList list(ident.begin(), ident.end());
It is however more than slightly wasteful to create a labelList
just for initializing a scalarList. An alternative could be a
a labelRange for the same purpose.
labelRange ident = labelRange::identity(12345);
scalarList list(ident.begin(), ident.end());
Or this
scalarList list
(
labelRange::null.begin(),
labelRange::identity(12345).end()
);
- provides const/non-const access to the underlying list, but the
iterator access itself is const.
- provide linked-list iterator 'found()' method for symmetry with
hash-table iterators. Use nullptr for more clarity.
- lookup(): with a default value (const access)
For example,
Map<label> something;
value = something.lookup(key, -1);
being equivalent to the following:
Map<label> something;
value = -1; // bad value
if (something.found(key))
{
value = something[key];
}
except that lookup also makes it convenient to handle const references.
Eg,
const labelList& ids = someHash.lookup(key, labelList());
- For consistency, provide a two parameter HashTable '()' operator.
The lookup() method is, however, normally preferable when
const-only access is to be ensured.
- retain(): the counterpart to erase(), it only retains entries
corresponding to the listed keys.
For example,
HashTable<someType> largeCache;
wordHashSet preserve = ...;
largeCache.retain(preserve);
being roughly equivalent to the following two-stage process,
but with reduced overhead and typing, and fewer potential mistakes.
HashTable<someType> largeCache;
wordHashSet preserve = ...;
{
wordHashSet cull(largeCache.toc()); // all keys
cull.erase(preserve); // except those to preserve
largeCache.erase(cull); //
}
The HashSet &= operator and retain() are functionally equivalent,
but retain() also works with dissimilar value types.
- less clutter and typing to use the default template parameter when
the key is 'word' anyhow.
- use EdgeMap instead of the longhand HashTable version where
appropriate
- ensure that each have found() and which() methods
- add faceTraits for handling compile-time differences between
'normal' and tri-faces
- provide line::unitVec method (complimentary to edge::unitVec)
- provide key_iterator/const_key_iterator for all hashes,
reuse directly for HashSet as iterator/const_iterator, respectively.
- additional keys() method for HashTable that returns a wrapped to
a pair of begin/end const_iterators with additional size/empty
information that allows these to be used directly by anything else
expecting things with begin/end/size. Unfortunately does not yet
work with std::distance().
Example,
for (auto& k : labelHashTable.keys())
{
...
}
- add increment/decrement, repositioning. Simplify const_iterator.
- this makes is much easier to use labelRange for constructing ranges of
sub-lists. For symmetry with setSize() it has a setStart() instead of
simply assigning to start() directly. This would also provide the
future possibility to imbue the labelRange with a particular policy
(eg, no negative starts, max size etc) and ensure that they are
enforced.
A simple use case:
// initialize each to zero...
List<labelRange> subListRanges = ...;
// scan and categorize
if (condition)
subListRanges[categoryI]++; // increment size for that category
// finally, set the starting points
start = 0;
for (labelRange& range : subListRanges)
{
range.setStart(start);
start += range.size();
}
