`ArrayHandleCounting` only works with values that support basic
arithmetic. The concept of counting makes little sense for types that
are not well defined for addition and multiplication like `bool`,
`string` and other custom types.
`RecombineVec` is the class used as the value type for
`ArrayHandleRecombineVec`. It is a `Vec`-like object, but has several
limitations (including arithmetic operators like `+` won't work).
Arithmetic assignment operators are useful so you don't have to create
impossible intermediate values.
Previously, the arithmetic assignment operators (`+=`, `-=`, `*=`, `/=`)
on `VecBaseCommon` only accepted another subclass of `VecBaseCommon`.
Changed the operators to accept any type.
The benefit of this change is that the assignment operator of classes
that inherit from `VecBaseCommon` can now work with `Vec`-like classes
that do not inherit from `VecBaseCommon`. I think the only real downside
is that the template could match other classes that would lead to
invalid comparisons. But such use would lead to a compile error anyway.
The difference is that instead of getting an error that no overloaded
version of the operator is available, you will get an error inside the
code of the operator.
The base C types have several "duplicate" types that the compiler
considers different even though the byte representation is the same. For
example, `char` and `signed char` have the same meaning but are treated
as different types. Likewise, 'long', 'int', and 'long long' are all
different types even though 'long' is the same as either 'int' or 'long
long'.
When pulling extracted components from `UnknownArrayHandle`, there is
little value for creating multiple code paths for types like `char` and
`signed char`. Instead, allow implicit conversion among these types.
When using the old style of storage, you need to declare it as the old
style so that a bridge to the new style can be built in. You get a
compile error message if this is not done. The previous message gave the
wrong instructions.
What was previously declared as `ArrayHandleNewStyle` is now just the
implementation of `ArrayHandle`. The old implementation of `ArrayHandle`
has been moved to `ArrayHandleDeprecated`, and `ArrayHandle`s still
using this implementation must declare `VTKM_ARRAY_HANDLE_DEPRECATED` to
use it.
Some organizations use a firewall that intercepts SSL communications and
replaces the authentication token with an organization-wide token that
is just supposed to be accepted. Browsers can be locally configured for
this intentional trickery, but it's a little more tricky for the use of
`curl` in a batch script that is shared with external collaborators.
The easiest solution is to just disable the security for the `curl`
download. This makes the script more susceptible to "man in the middle"
attacks, but it's probably easier to just slip malware in the public
repos anyway.
Some of the special `ArrayHandle`s require specialized versions of
`vtkm::exec::arg::Fetch`. The specializations were not put in the
respective vtkm/exec/arg/Fetch*.h header files because the definition of
the `ArrayHandle`s was not available there. The implementation was in
the ArrayHandle*.h files, but it is hard to find the specialization
there.
Instead, make a secondary header file in vtkm/exec/arg that implements
the Fetch specialization and include it from the ArrayHandle*.h file.
That way, the basic Fetch does not have to include odd `ArrayHandle`
types but the `Fetch` implemenations are still all located together.
This method was originally deprecated to avoid confusion with the
indexing of the components in `ExtractComponent`. However, there might
be good reason to want to know the non-flat number of components, so
maybe getting rid of it is not a great idea. Unmark the method as
deprecated, at least for now.
Previously, `ArrayHandleSOA` worked with any value type that supported
`VecTraits`. That means that `ArrayHandleSOA` worked with scalar types
like `Float32`. However, for scalar types, the behavior is essentially
the same as `ArrayHandleBasic`, but with lots of extra templating and
code generation.
Although there is nothing _wrong_ with allowing `ArrayHandleSOA` holding
a scalar, there is no real reason to either (other than likely template
convenience). Generally, there is nothing wrong with supporting it, but
if you want to support `ArrayHandleSOA` in places where types are not
known (e.g. `Field`), then templating tends to iterate over the cross of
all supported types with all supported storage. That means such code
will automatically generate a bunch of code for `ArrayHandleSOA` with
scalars even if there is no reason for those code paths.
So, we can just disable the use of `ArrayHandleSOA` with scalars to
allow us to use `ArrayHandleSOA` as a default storage without creating
all these useless code paths.
`ArrayHandleRecombineVec` is used when calling
`ExtractArrayFromComponents` from `UnkownArrayHandle`. It needs special
handling with the `Fetch` for an output array.
