- with '&&' conditions, often better to check for non-null autoPtr
first (it is cheap)
- check as bool instead of valid() method for cleaner code, especially
when the wrapped item itself has a valid/empty or good.
Also when handling multiple checks.
Now
if (ptr && ptr->valid())
if (ptr1 || ptr2)
instead
if (ptr.valid() && ptr->valid())
if (ptr1.valid() || ptr2.valid())
- The writers have changed from being a generic state-less set of
routines to more properly conforming to the normal notion of a writer.
These changes allow us to combine output fields (eg, in a single
VTK/vtp file for each timestep).
Parallel data reduction and any associated bookkeeping is now part
of the surface writers.
This improves their re-usability and avoids unnecessary
and premature data reduction at the sampling stage.
It is now possible to have different output formats on a per-surface
basis.
- A new feature of the surface sampling is the ability to "store" the
sampled surfaces and fields onto a registry for reuse by other
function objects.
Additionally, the "store" can be triggered at the execution phase
as well
- now placed under postProcessing/checkMesh and postProcessing/checkAMI,
respectively.
Output files are now also tagged with the id of the patch, in case
there are multiple AMI patches in use.
Improve alignment of its behaviour with std::unique_ptr
- element_type typedef
- release() method - identical to ptr() method
- get() method to get the pointer without checking and without releasing it.
- operator*() for dereferencing
Method name changes
- renamed rawPtr() to get()
- renamed rawRef() to ref(), removed unused const version.
Removed methods/operators
- assignment from a raw pointer was deleted (was rarely used).
Can be convenient, but uncontrolled and potentially unsafe.
Do allow assignment from a literal nullptr though, since this
can never leak (and also corresponds to the unique_ptr API).
Additional methods
- clone() method: forwards to the clone() method of the underlying
data object with argument forwarding.
- reset(autoPtr&&) as an alternative to operator=(autoPtr&&)
STYLE: avoid implicit conversion from autoPtr to object type in many places
- existing implementation has the following:
operator const T&() const { return operator*(); }
which means that the following code works:
autoPtr<mapPolyMesh> map = ...;
updateMesh(*map); // OK: explicit dereferencing
updateMesh(map()); // OK: explicit dereferencing
updateMesh(map); // OK: implicit dereferencing
for clarity it may preferable to avoid the implicit dereferencing
- prefer operator* to operator() when deferenced a return value
so it is clearer that a pointer is involve and not a function call
etc Eg, return *meshPtr_; vs. return meshPtr_();
- relocated ListAppendEqOp and ListUniqueEqOp to ListOps::appendEqOp
and ListOps::UniqueEqOp, respectively for better code isolation and
documentation of purpose.
- relocated setValues to ListOps::setValue() with many more
alternative selectors possible
- relocated createWithValues to ListOps::createWithValue
for better code isolation. The default initialization value is itself
now a default parameter, which allow for less typing.
Negative indices in the locations to set are now silently ignored,
which makes it possible to use an oldToNew mapping that includes
negative indices.
- additional ListOps::createWithValue taking a single position to set,
available both in copy assign and move assign versions.
Since a negative index is ignored, it is possible to combine with
the output of List::find() etc.
STYLE: changes for PackedList
- code simplication in the PackedList iterators, including dropping
the unused operator() on iterators, which is not available in plain
list versions either.
- improved sizing for PackedBoolList creation from a labelUList.
ENH: additional List constructors, for handling single element list.
- can assist in reducing constructor ambiguity, but can also helps
memory optimization when creating a single element list.
For example,
labelListList labels(one(), identity(mesh.nFaces()));
- add copy construct from UList
- remove copy construct from dissimilar types.
This templated constructor was too generous in what it accepted.
For the special cases where a copy constructor is required with
a change in the data type, now use the createList factory method,
which accepts a unary operator. Eg,
auto scalars = scalarList::createList
(
labels,
[](const label& val){ return 1.5*val; }
);
- Allows passing of additional information (per-face zone ids) or possibly
other things, while reducing the number of arguments to pass.
- In sampledTriSurfaceMesh, preserve the region information that was
read in, passing it onwards via the UnsortedMeshSurface content.
The Nastran surface writer is currently the only writer making use
of this per-face zone information.
Passing it through as a PSHELL attribute, which should retain the
distinction for parts. (issue #204)
- the checking for point-connected multiple-regions now also writes the
conflicting points to a pointSet
- with the -writeSets option it now also reconstructs & writes pointSets
In parallel the sets are reconstructed. e.g.
mpirun -np 6 checkMesh -parallel -allGeometry -allTopology -writeSets vtk
will create a postProcessing/ folder with the vtk files of the
(reconstructed) faceSets and cellSets.
Also improved analysis of disconnected regions now also checks for point
connectivity with is useful for detecting if AMI regions have duplicate
points.
Patch contributed by Mattijs Janssens
- checkMesh has option to write faceSets or (outside of) cellSets as
sampledSurface format. It automatically reconstructs the set on the master
and writes it to the postProcessing folder (as any sampledSurface). E.g.
mpirun -np 6 checkMesh -allTopology -allGeometry -writeSets vtk -parallel
- fixed order writing of symmTensor in Ensight writers
