/** \\file
26
* \\brief The FunctionNodes are node class that takes as a paramater a
27
* function object.
28
*
29
* The end user should never use these but instead be calling Kernel::CreateFunctionNode
30
* Don't edit this file, edit FunctionNode.py and then manual recreate this file.
31
* Note sections of this file needs to be manually moved to Kernel.h.
32
* This file should not need to change very often.
33
* Things where done this way because C++ doesn't have vararg templates (well
34
* at least the version we are using doesn't).
