Added a BaseComponentType to VecTraits that recursively finds the base
(non-Vec) type of a Vec. This is useful when dealing with potentially
nested Vec's (e.g. Vec<Vec<T, M>, N>) and you need to keep the structure
but know the base type.
Also added a couple of templates for keeping the structure but changing
the type. These are ReplaceComponentType and ReplaceBaseComponentType.
These allow you to create new Vec's with the same structure as the query
Vec but with differen component types.
1. Add a 'FastVec' class that copies input vector types to an efficient
Vec type on the stack. Specializations avoid copies of already efficient
types.
2. Update 'WorldCoordinatesToParametricCoordinates' functions to utilize the
'FastVec' class. This should improve performance when the passed in
vectors are of slow types like 'vtkm::VecFromPortalPermute'.
3. Since most input Vec types will convert to the same 'FastVec' type this
also reduces the code generations. Some code refactoring was required for
this.
Sandia National Laboratories recently changed management from the
Sandia Corporation to the National Technology & Engineering Solutions
of Sandia, LLC (NTESS). The copyright statements need to be updated
accordingly.
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.
Add in the vtkm namespace an assert macro (technically VTKM_ASSERT) that
basically replicates the functionality of the POSIX assert macro. This
form of assert is set to replace the separate control/exection asserts.
It has been decided that an assert that throws an exception instead of
terminating the program is not all that great of a feature and it causes
some limitations on how it is used. The next commit will remove the
other forms of VTK-m assert.
This class holds a Vec and exposes some number of components. The class
is used when you need a Vec of a size that is not known at compile time
but that a maximum length of reasonable size is known.
