This is rather technical question on how to approach it.
I ask because I work with 3rd party doc block parser and need to build the same feature around it.

Input

The parser returns Nodes (ParamNode for @param Type $name, VarNode etc.),
and lexer returns tokens (/**, , @, param ...).

Change

Let's say I change Type to TypeFoo via $paramNode->type (like here).

How to connect them together so I could print back the original format?

If that helps, I'm aware there is indent in printer and each node has original node on it.

Thank you for any guidance.
