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.

|
|
/// \c ArrayPortalToIterators is a class that holds an \c ArrayPortal and
|
|
/// builds iterators that access the data in the \c ArrayPortal. The point of
|
|
/// this class is to use an \c ArrayPortal with generic functions that expect
|
|
/// STL iterators such as STL algorithms or Thrust operations.
|
|
///
|
|
/// The default template implementation constructs iterators that provide
|
|
/// values through the \c ArrayPortal itself. This class can be specialized to
|
|
/// provide iterators that more directly access the data. For example, \c
|
|
/// ArrayPortalFromIterator has a specialization to return the original
|
|
/// iterators.
