Execute Callback after Plugin Finishes

Hello,

I’m building a plugin with similar structure to the example “PrintFunctionNames.”
I would like to run a function when my plugin has finished executing, i.e., after it has traversed all the decls and visited all statements, etc.

Is there a method I can override or some other callback mechanism in PluginASTAction, ASTConsumer, or RecursiveASTVisitor that will execute at the very end of the plugin? Any alternative way to do so (outside of those classes) is fine as well.

Thanks in advance,
Kevin Boos
