◆ RedeclLink

template<typename decl_type>
DeclLink clang::Redeclarable< decl_type >::RedeclLink
protected

Points to the next redeclaration in the chain.

If NextIsPrevious() is true, this is a link to the previous declaration of this same Decl. If NextIsLatest() is true, this is the first declaration and Link points to the latest declaration. For example:

#1 int f(int x, int y = 1); // <pointer to #3, true> #2 int f(int x = 0, int y); // <pointer to #1, false> #3 int f(int x, int y) { return x + y; } // <pointer to #2, false>

If there is only one declaration, it is <pointer to self, true>
