- there were previously no hashing mechanisms for lists so they
would fall back to the definition for primitives and hash the
memory location of the allocated List object.
- provide a UList::Hash<> sub-class for inheritance, and also a global
specialization for UList<T>, List<T> such that the hash value for
List<List<T>> cascades properly.
- provide similar function in triFace to ensure that it remains
similar in behaviour to face.
- added SymmHash to Pair, for use when order is unimportant.
STYLE: use string::hash() more consistently
- no particular reason to use Hash<word>() which forwards to
string::hash() anyhow
- With argList::noFunctionObjects() we use the logic added in
4b93333292 (issue #352)
By removing the '-noFunctionObjects' option, we automatically
suppress the creation of function-objects via Time (with argList
as a parameter).
There is generally no need in these cases for an additional
runTime.functionObjects().off() statement
Use the argList::noFunctionObjects() for more direct configuration
and reduce unnecessary clutter in the -help information.
In previous versions, the -noFunctionObjects would have been redundant
anyhow, so we can also just ignore it now instead.
- allows use with any container with begin(), end() and where the
"*iterator" dereference returns a label, which is used for indexing
into the list of points.
This container could be labelUList, bitSet, labelHashSet, etc
- takes a direct approach of determining which cells are cut and walks
the cell faces directly to build the resulting surface.
- better handling of corner cases.
* Avoids redundant points when the cut passes exactly through a
mesh point.
* Supresses generation of duplicates faces when the plane cut
coincides exactly with a mesh face.
- for severely concave cells where the plane cuts a face multiple times
there is currently no remedial action taken, except to note the
failure and unwind the insertion of the corresponding points and
faces.
- signedDistance() method is like distance() but retains
the positive/negative sign for the side of the plane.
- the sign() method returns the sign as -1,0,+1 integer for
classification purposes where it is important to distinguish between
a zero value and a positive value (eg, for cutting). Optional
tolerance can be supplied to round for zero.
- refactor and inlined simple and frequently used methods.
- add boundBox faceCentre() method, which can be useful for creating
clipping planes from a bounding box.
Relocated treeBoundBox faceNormals to boundBox since they apply
equally there - the meaning of the faces (x-min, x-max, etc)
is the same, even if the point addressing for the faces differs.
