      The hash code of the current type.

    • clone

      public final SyntaxNode clone()
      Clones the syntax node if the node is mutable.
      Overrides:
      clone in class Object
      Returns:
      If the node is mutable, returns the cloned object. Otherwise, returnsthe equivalent object from object pool.
