The ordering is that of the iterator() method on the collection.- Type Parameters:
- T- the object type
- Parameters:
- transformers- a collection of transformers to chain
- Returns:
- the chainedtransformer
- Throws:
- NullPointerException- if the transformers collection is null
- NullPointerException- if any transformer in the collection is null

- Returns:
- the chainedtransformer
- Throws:
- NullPointerException- if the transformers array is null
- NullPointerException- if any transformer in the array is null
