I have get stuck in a problem about a simple code.
for example:
I defined a function

combustion::tmp<volScalarField>sh() const;

when I tried to call the function:
(1)combustion->sh()
(2)combustion->sh()()

what's the difference between the two forms?

Best regards

As far as I understand the first one calls operator() on sh. The second one calls operator() on the return value of sh(). What's your intention?

Dear cutter,
Thank you for your reply.

The reason why I was wondering is the change of version.

There is a same solver, chemistry.sh()() in openfoam 1.7, but combustion->sh() in openfoam 2.0,2.1

I was wondering whether the different forms express the same meanings or not.
