Change the VTKM_CONT_EXPORT to VTKM_CONT. (Likewise for EXEC and
EXEC_CONT.) Remove the inline from these macros so that they can be
applied to everything, including implementations in a library.
Because inline is not declared in these modifies, you have to add the
keyword to functions and methods where the implementation is not inlined
in the class.
VTK-m style guidelines dictate that all classes part of the API should
be in their own header file. Thus, we have moved the result classes out
of the filter header files and into their own headers.
We have also renamed these clases to ResultField and ResultDataSet to
better match the class naming conventions of VTK-m.
Since we are moving around these result classes, we have also revamped
their structure. They are now in a hierarchy with a common ResultBase
class. Additionally, all result classes have a reference to a complete
DataSet that can be considered the output of the filter. This will make
it easier for users to consistently deal with filter results.
These changes cover issues #60 and #62.
These asserts are consolidated into the unified Assert.h. Also made some
minor edits to add asserts where appropriate and a little bit of
reconfiguring as found.
Make it match VTKDataSetReader better. It's also a bit easier to use
because you just have to give it a filename rather than open your own file
stream.
We have been using the term "shape" in the cell set and connectivity
classes. To be consistent, use the term "shape" for the geometric
identify of the cell everywhere.
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.
The Invoke of the topology dispatcher is also changed to expect a
concrete cell set (which the DynamicCellSet is automatically cast to)
rather than a connectivity structure. The dispatcher calls the
GetNodeToCellConnectivity method for you. (That is currently the only
one supported.)
The most common changes were making class members uppercase and spelled
out, adding "this->" whenever a class member is used, and declare
functions and members with export macros. Also fixed some uses of int
(instead of vtkm::Id or something similar) and a bit of indentation. I
also sprinkled some const goodness over the code.
It should be noted that I had about a week delay between first making
these changes and checking them in. In the mean time Sujin also made
some similar changes, so there might be some repetative changes.
