All Implemented Interfaces:
    UnnamedParametric

Component for AppendIteratorTag, which jobs is to append iterators to form an appended iterator whereby entries goes from one iterator to another after each respective iterator is exhausted of entries.

For example, if there are 3 iterator appended (each iterator has 3 entries), the following will be how the appended iterator entries will be arranged:

  1. First Entry of the First Iterator
  2. Second Entry of the First Iterator
  3. Third Entry of the First Iterator
  4. First Entry of the Second Iterator
  5. Second Entry of the Second Iterator
  6. Third Entry of the Second Iterator
  7. First Entry of the Third Iterator
  8. Second Entry of the Third Iterator
  9. Third Entry of the Third ITerator
