There are several tests in the cont directory that are in header files so
that they can be recompiled for different devices. Make sure that the
tests are exclusively using the device being tested by making the error
device adapter the default.
If any part of the test tries to use the default device (which could be
different than the one being tested), a compile error will occur. Several
of these compile errors are fixed in this commit.
The PrintSummary for CoordinateSystem went in an infinite loop. It was
supposed to call PrintSummary of its superclass (Field), but instead it
called itself.
The PrintSummary for Field only worked for fields of type vtkm::Float32.
To make it work for all array types, I added a PrintSummary method to
DynamicArrayHandle, and Field calls that without trying to cast to a
static type.
Previously, coordinate systems in a DataSet simply pointed to field data
specifying the coordinate information (although the ability to get that
back out of the DataSet was missing). This makes sense since point
coordinates are in fact just fields with a particular semantic meaning
to them.
However, there is an issue with this approach. It turns out that there
are special representations that are very common for point coordinates
and very uncommon for other types of fields. For example, a uniform
(a.k.a. regular or image) grid has point coordinates that are easily
derived from the point index, but such fields are quite uncommon
elsewhere.
Representing this kind of structure in the Field list of a DataSet is
problematic. Either all fields have to check to see if they are this
type, which will cause an explosion of unnecessary generated code, or
you will have to actually write out the coordinates in memory, which is
really wasteful but what was done previously.
However, by storing fields representing coordinate systems in a separate
batch, we can use these special types without the stated explosion.
