  - ### Method Detail

    - #### public static void doExtendTraits(ClassNode cNode, SourceUnit unit, CompilationUnit cu)

      Given a class node, if this class node implements a trait, then generate all the appropriate code which delegates calls to the trait. It is safe to call this method on a class node which does not implement a trait.

      Parameters:
        `cNode` - a class node
        `unit` - the source unit
