- the expansions were previously required as slash to follow, but
now either are possible.
"<case>", "<case>/" both yield the same as "$FOAM_CASE" and
will not have a trailing slash in the result. The expansion of
"$FOAM_CASE/" will however have a trailing slash.
- adjust additional files using these expansions
- both autoPtr and tmp are defined with an implicit construct from
nullptr (but with explicit construct from a pointer to null).
Thus is it safe to use 'nullptr' when returning an empty autoPtr or tmp.
- when constructing dimensioned fields that are to be zero-initialized,
it is preferrable to use a form such as
dimensionedScalar(dims, Zero)
dimensionedVector(dims, Zero)
rather than
dimensionedScalar("0", dims, 0)
dimensionedVector("zero", dims, vector::zero)
This reduces clutter and also avoids any suggestion that the name of
the dimensioned quantity has any influence on the field's name.
An even shorter version is possible. Eg,
dimensionedScalar(dims)
but reduces the clarity of meaning.
- NB: UniformDimensionedField is an exception to these style changes
since it does use the name of the dimensioned type (instead of the
regIOobject).
This class is largely a pre-C++11 holdover. It is now possible to
simply use move construct/assignment directly.
In a few rare cases (eg, polyMesh::resetPrimitives) it has been
replaced by an autoPtr.

* additional reference access methods:
cref()
returns a const reference, synonymous with operator().
This provides a more verbose alternative to using the '()' operator
when that is desired.
Mnemonic: a const form of 'ref()'
constCast()
returns a non-const reference, regardless if the underlying object
itself is a managed pointer or a const object.
This is similar to ref(), but more permissive.
Mnemonic: const_cast<>
Using the constCast() method greatly reduces the amount of typing
and reading. And since the data type is already defined via the tmp
template parameter, the type deduction is automatically known.
Previously,
const tmp<volScalarField>& tfld;
const_cast<volScalarField&>(tfld()).rename("name");
volScalarField& fld = const_cast<volScalarField&>(tfld());
Now,
tfld.constCast().rename("name");
auto& fld = tfld.constCast();

BUG: attempts to move tmp value that may still be shared.
- old code simply checked isTmp() to decide if the contents could be
transfered. However, this means that the content of a shared tmp
would be removed, leaving other instances without content.
* movable() method checks that for a non-null temporary that is
unique (not shared).
* For most cases, this conversion would be largely unintentional
and also less efficient. If the regex is desirable, the caller
should invoke it explicitly.
For example,
findStrings(regExp(str), listOfStrings);
Or use one of the keyType, wordRe, wordRes variants instead.
If string is to be used as a plain (non-regex) matcher,
this can be directly invoked
findMatchingStrings(str, listOfStrings);
or using the ListOps instead:
findIndices(listOfStrings, str);
* provide function interfaces for keyType.
