Makes a new copy of this nonleaf-node as a ptree-node. The objects contained by the new object are same as these contained by the original object.

Specified by:

makeCopy in interface ParseTree

Overrides:

makeCopy in class ParseTreeObject

---

This invoke an appropriate visit() method on the accepted visitor.

Specified by:

accept in interface ParseTree

Specified by:

accept in class ParseTreeObject
