Specified by:treeCopyNoTransform in class TypeDecl
Returns:
dangling copy of the subtree at this node
Source
Declared in /home/jesper/git/extendj/ASTNode at line 96
public NullType treeCopy()
Create a deep copy of the AST subtree at this node. The subtree of this node is traversed to trigger rewrites before copy. The copy is dangling, i.e. has no parent.
Specified by:treeCopy in class TypeDecl
