- returns UPtrList view (read-only or read/write) of the objects
- shorter names for IOobject checks: hasHeaderClass(), isHeaderClass()
- remove unused IOobject::isHeaderClassName(const word&) method.
The typed versions are preferable/recommended, but can still check
directly if needed:
(io.headerClassName() == "foo")
- use succincter method names that more closely resemble dictionary
and HashTable method names. This improves method name consistency
between classes and also requires less typing effort:
args.found(optName) vs. args.optionFound(optName)
args.readIfPresent(..) vs. args.optionReadIfPresent(..)
...
args.opt<scalar>(optName) vs. args.optionRead<scalar>(optName)
args.read<scalar>(index) vs. args.argRead<scalar>(index)
- the older method names forms have been retained for code compatibility,
but are now deprecated
- Recursive searching for objects within a registry is now optional
(previous it was always done).
A recursive search effectively blocks the construction of sub-sub-registries
if their names are 'masked' by some parent level sub-registry with
the same name! (BUG)
- Recursive search is now turned OFF by default, which makes it consistent
with dictionary and probably causes the least number of surprises.

Various new convenience methods added:
lookupObjectRef()
- returns a non-const reference.
For example,
volScalarField& U = mesh().lookupObjectRef<volScalarField>("U");
Instead of
volScalarField& U = const_cast<volScalarField&>
(
mesh().lookupObject<volScalarField>("U")
);
--
lookupObjectPtr()
- returns a const pointer, and nullptr on failure.
For example,
const volScalarField* Uptr = mesh().lookupObjectPtr<volScalarField>("U");
if (Uptr)
{
const volScalarField& U = *Uptr;
...
}
Instead of
if (mesh().foundObject<volScalarField>("U"))
{
const volScalarField& U = mesh().lookupObject<volScalarField>("U");
...
}
--
lookupObjectRefPtr()
- returns a non-const pointer, and nullptr on failure.
For example,
volScalarField* Uptr = mesh().lookupObjectRefPtr<volScalarField>("U");
if (Uptr)
{
volScalarField& U = *Uptr; // use as reference
(*Uptr) = ...; // or use directly
}
Instead of
if (mesh().foundObject<volScalarField>("U"))
{
volScalarField& U = const_cast<volScalarField&>
(
mesh().lookupObject<volScalarField>("U")
);
}
--
sortedNames()
- now works with template parameters and with regular expression
matching as well.
For example,
wordList names = mesh().sortedNames();
wordList fields = mesh().sortedName<volScalarField>();
Instead of
wordList names = mesh().sortedNames();
wordList fields = mesh().names<volScalarField>();
Foam::sort(fields);
