- makes the intent clearer and avoids the need for additional
constructor casting. Eg,
labelList(10, Zero) vs. labelList(10, 0)
scalarField(10, Zero) vs. scalarField(10, scalar(0))
vectorField(10, Zero) vs. vectorField(10, vector::zero)
- cfindObject() for const pointer access.
- getObject() for mutable non-const pointer access, similar to the
objectRegistry::getObjectPtr()
- cfindObject(), findObject(), getObject() with template type access
to also check the headerClassName.
For example,
cfindObject("U") -> good
cfindObject<volVectorField>("U") -> good
cfindObject<volScalarField>("U") -> nullptr
This allows inversion of looping logic.
1) Obtain the names for a particular Type
for (const word& objName : objs.sortedNames<Type>())
{
const IOobject* io = objs[objName];
...
}
2) Use previously obtained names and apply to a particular Type
for (const word& objName : someListOfNames)
{
const IOobject* io = objs.cfindObject<Type>(objName);
if (io)
{
...
}
}
