copy

IASTExpression copy()

Description copied from interface: IASTNode

Returns a mutable copy of the tree rooted at this node. The following postconditions hold: copy.getParent() == null copy.getPropertyInParent() == null copy.isFrozen() == false Preprocessor nodes do not currently support being copied. Implicit name nodes are not copied, instead they can be regenerated if required.
