- Exception classes cannot be exported due to MSVC's design decisions. See http://stackoverflow.com/questions/24511376. We must leave these classes as header only and silence the warnings. - TransferResource in BufferState.h must remain a header-only class since there is no vtkm_interop library to compile the class into. - The VTKDataSetReader hierarchy must similarly remain header-only since there is no vtkm_io library. - The OptionParser Action classes are part of a header-only utility and cannot be easily compiled into a library. -

// Background:
|
|
// VTK-m libraries are built with the hidden symbol visibility by default.
|
|
// This means that all template classes that are defined in VTK-m headers are
|
|
// defined with hidden visibility when we are building VTK-m. But when those
|
|
// headers are included by a third-party which has differing visibility controls
|
|
// causing link time warnings ( external vs private ).
|
|
//
|
|
// Issue:
|
|
// Dynamic cast is not just based on the name of the class, but also the
|
|
// combined visibility of the class on OSX. When building the hash_code of
|
|
// an object the symbol visibility controls of the type are taken into
|
|
// consideration ( including symbol vis of template parameters ).
|
|
// Therefore if a class has a component with private/hidden vis than it
|
|
// can't be passed across library boundaries.
|
|
//
|
|
// Example is PolymorphicArrayHandleContainer<T,S> whose visibility affected
|
|
// by the visibility of both T and S.
|
|
//
|
|
// Solution:
|
|
// The solution is fairly simple, but annoying. You need to mark
|
|
//
|
|
// TL;DR:
|
|
// This markup is used when we want to make sure:
|
|
// - The class can be compiled into multiple libraries and at runtime will
|
|
// resolve to a single type instance
|
|
// - Be a type ( or component of a types signature ) that can be passed between
|
|
// dynamic libraries and requires RTTI support ( dynamic_cast ).
