previously the store() method just set the ownedByRegistry flag. Now ensure that it is indeed registered first.

support register/store of tmp<> items. The tmp parameter is not cleared, but changed from PTR to CREF to allow further use.

The implicit registration allows code simplification using the GeometricField::New factory method, for example.

Old Code

volScalarField* ptr = new volScalarField
(
    IOobject
    (
        fieldName,
        mesh.time().timeName(),
        mesh,
        IOobject::NO_READ,
        IOobject::NO_WRITE,
        true  // Register
    ),
    mesh,
    dimless,
    zeroGradientFvPatchField<scalar>::typeName
);
ptr->store();

New Code

auto tptr = volScalarField::New
(
    fieldName,
    mesh,
    dimless,
    zeroGradientFvPatchField<scalar>::typeName
);
regIOobject::store(tptr);

or even regIOobject::store ( volScalarField::New ( fieldName, mesh, dimless, zeroGradientFvPatchField::typeName ) );
