Subject: put VPSC’s Node class in an anonymous namespace
X-Git-Tag: 2.47.3~25^2~4
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=329c674817d06f874246f465c3fb9840e5494809;p=graphviz

put VPSC’s Node class in an anonymous namespace

This marks the class as unnecessary outside of its containing translation unit.
This further emphasizes that is is an implementation detail of the containing
file as well as allowing the compiler to aggressively optimize its layout.
