- !ruby/struct:SM::Flow::P 
  body: Rebuilds the hash based on the current hash values for each key. If values of key objects have changed since they were inserted, this method will reindex <em>hsh</em>. If <tt>Hash#rehash</tt> is called while an iterator is traversing the hash, an <tt>IndexError</tt> will be raised in the iterator.
