|
* scan the design but not transform it in any way.
|
|
*
|
|
* When a functor it scanning a process, signal or node, the functor
|
|
* is free to manipulate the list by deleting items, including the
|
|
* node being scanned. The Design class scanner knows how to handle
|
|
* the situation. However, if objects are added to the netlist, there
|
|
* is no guarantee that object will be scanned unless the functor is

|
* rerun.
