Because ArrayPortalSOA calls a delegate portal to get the actual values,
it can only implement its own Set or Get if the delegate portal supports
it. Previously this was done by calling an overloaded internal method
based on the result of PortalSupportsSets/Gets. However, regardless of
whether the delegate portal supported Set or Get, ArrayPortalSOA
provided one. Thus, if something else tried to use PortalSupportsSets/
Gets on ArrayPortalSOA, it would always report true even if it was not
really supported.
Instead, use SFINAE to remove the Set or Get if that method is not
supported in the delegate portal.
Since ArrayHandleSOA is only really used for portals from basic storage
arrays, it will be rare that Set or Get is not supported. However, a
device adapter is free to remove one of these methods on a device
portal. For example, if you call PrepareForInput on an ArrayHandle, it
is possible that the device adapter will create a portal that has no Set
method because the array is not writable.
Thanks to Allison Vacanti for recomending this solution.
I kept getting warnings from different compilers about type conversions
because I was making values by adding an index to them. Change how we
create and test values so that these type issues are less likely to come
up.
Apparently, the Visual Studio 2015 has a bug where the result of a
decltype might not be considered a type. Attempt to get around this
problem by putting the decltype inside of a struct and then have the
using statement use the typename keyword. Hopefully if you literally say
that something is a typename, the compiler will treat it like a type
name.
The gradient is malformed at the apex of a pyramid. To get around this,
steal a trick from the VTK source where in this case interpolate some
values a little bit into the interior of the cell.
Also expand the gradient worklet tests to include all cell types.
To help provide a better time writing VTK-m filter this streamlines
the CreateResult API to provide a focused set of methods, based on
how CreateResult has been used by existing filters.
TypeListTagAll only defines vectors up to size 4, while the default
filter traits do not restrict input types at all.
Since the moments computation may use 6- or 9-tuple vecs, this
restriction is breaking those usecases.
