* Fix several bugs with processing templates in ICG - Fixed an issue where io_src code for some templates was being placed in the wrong file. - Fixed an issue with templates being instantiated with templates as parameters. - Fixed an issue with templates that instantiate templates. Added additional tests to cover these cases. * Moved the list of template argument header dependencies from ClassValues to PrintFileContents10 so they can be printed to the io_ file regardless of the order in which class info is printed. * Moved the list of template argument header dependencies from ClassValues to PrintFileContents10 so they can be printed to the io_ file regardless of the order in which class info is printed. Moved the list of template argument header dependencies from ClassValues to PrintFileContents10 so they can be printed to the io_ file regardless of the order in which class info is printed. * Added support to handle template enum class type argument and removed some commented code.

/**
|
|
|
|
This class is a recursive AST visitor that is called when a CXXRecordDecl node
|
|
is found. Inside of a CXXRecord we are only interested in 4 types of nodes, the
|
|
CXXRecord itself, template specializations, friends, and fields. If a field is
|
|
found a FieldVisitor is instantiated and parsing of the field continues in the
|
|
field visitor.
|
|
|
|
A class visitor is usually instantiated by the top level visitor, TranslationUnitVisitor,
|
|
or the typedef visitor, TypedefVisitor.
