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 HashSetPlusEqOp and HashTablePlusEqOp to
HashSetOps::plusEqOp and HashTableOps::plusEqOp, respectively
- additional functions for converting between a labelHashSet
and a PackedBoolList or List<bool>:
From lists selections to labelHashSet indices:
HashSetOps::used(const PackedBoolList&);
HashSetOps::used(const UList<bool>&);
From labelHashSet to list forms:
PackedBoolList bitset(const labelHashSet&);
List<bool> bools(const labelHashSet&);
- 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()));
- This class is largely a pre-C++11 holdover, prior to having movable
references.
- align internals with autoPtr instead of always unconditionally
allocating memory. The valid() method can be used to check for a null
pointer.
- Consolidate into a single file, in anticipation of future removal.
- rvalue() is a (transitional) means of converting Xfer content to a
reference for move construct, move assign semantics.
- valid() method for consistency with autoPtr and tmp classes
- simplify structure, removed unused constuctors.
- transfer from base objects via '=' assignment removed as being too
non-transparent
- add New factory method with perfect forwarding.
- the transfer method was previously a copy
- use std::reverse_iterator adaptors in FixedList
This greatly reduces the amount of code and now avoids the array-bounds
warning for FixedList::rend()
- use pointer arithmetic instead of dereferencing the internal array
- without these will use the normal move construct + move assign.
This is similarly efficient, but avoids the inadvertently having the
incorrect Swap being used for derived classes.
STYLE: remove unused xfer methods for HashTable, HashSet
- unneeded since move construct and move assignment are possible
- can stop producing content when the target number of entries has
been reached.
- change return type to labelList instead an Xfer container.
This allows return-value-optimization and avoids a surrounding
allocation. This potentially breaks existing code.
- make PackedList and PackedBoolList moveable. Drop xfer wrappers.
- problems when the cloud was not available on all processors.
- NB: ensight measured data only allows a single cloud, but
foamToEnsight writes all clouds.
- The central InfoSwitch "writeLagrangianPositions" allows writing an
additional Lagrangian "positions" file, but these were not being
written by reconstructPar. These are now also written in reconstructPar
if the central writeLagrangianPositions InfoSwitch is enabled.
NOTES
- "positions" are reconstructed from the processors "coordinates" file
- decomposePar will not attempt to create or redistribute any
"positions" files

alphaSuSp.H has to be added in the solver folder in order to make it compatible with the alpha Eq.
- required if there is no system openmp and libomp or libgomp are
only found in the clang hierarchy
STYLE: add some notes in the openmp rules.
- the _OPENMP macro is now used in low-level testing files
- The -rotate-angle option allows convenient specification of a
rotation about an arbitrary axis. Eg, -rotate-angle '((1 1 1) 45)'
- The -origin option can be used to temporarily shift the origin
for the rotation operations. For example,
-origin '(0 0 1)' -rotate-angle '((1 0 0) 180)'
for mirroring.
chtMultiRegionFoam now supports reaction/combustion modelling in fluid
regions in the same way as reactingFoam.
