iterator	back to summary
public Iterator<E> iterator() Implements groovy.lang.MetaClassRegistry.iterator. Returns an iterator to iterate over all constant meta classes. This iterator can be seen as making a snapshot of the current state of the registry. The snapshot will include all meta classes that has been used unless they are already collected. Collected meta classes will be skipped automatically, so you can expect that each element of the iteration is not null. Calling this method is thread safe, the usage of the iterator is not. Returns:Iterator<E> the iterator.
