Summary0000059: Size control in DynamicField
DescriptionIs there a possibility of having a templated size-control option (i.e., using a SizeInc/SizeMult/SizeDiv) for DynamicField, similar to the DynamicList approach? It would be better than blindly increasing the size of the field by 2, like it is right now.

I don't see this being an issue from a programming stand-point, but it would be a nice feature to have.

A less urgent feature-request would be to implement features that have been left out of DynamicField (like the remove() member, clearStorage(), etc..)
TagsNo tags attached.

DynamicField is lagging a bit with respect to DynamicList. Feel free to add the missing bits (also the size control) and send them to me.

I've uploaded the modifications with (most of) the missing bits. It mostly mimics the DynamicList functionality, but I was unsure about adding other Field functions like xfer(), transfer(), map(), rmap(), etc... I guess the inheritance hierarchy takes care of those for the moment, but pointer bugs may arise if we're not careful, so I leave that analysis to you.

I also noticed that the constructor for DynamicList specifies an over-ride for the underlying size:

template<class T, unsigned SizeInc, unsigned SizeMult, unsigned SizeDiv>
inline Foam::DynamicList<T, SizeInc, SizeMult, SizeDiv>::DynamicList
    const label nElem
    // we could also enforce SizeInc granularity when (!SizeMult || !SizeDiv)
    List<T>::size(0); <--- Shouldn't this not be there??

I agree that memory is un-initialized, but it gives the false impression that the List is sized to 'nElem', while it's artificially set to zero. Is this behaviour intentional?

I've updated DynamicField (commit 96dcbab7e165db56d78f36d14349b7db9777e1ea).

- I've removed the tmp handling - do you need it?
- the List::size(0) is intentional. That constructor just allocates memory which you then can fill with 'append'.

I guess this level of functionality should suffice for now, thanks.
