class AsIterator a

Types that are converted to an iterator by org.apache.tinkerpop.gremlin.util.iterator.IteratorUtils.asIterator method. In fact, that method can convert any type to an iterator, but greskell limits types to which the conversion is applicable.

Associated with this type-class is IteratorItem. IteratorItem type family is association of type a and the type of its item when type a is converted to an iterator.

IteratorItem rule of thumb:

• Iterator and Iterable types like List, Stream and GraphTraversal are converted to their element types.
• Map type is converted to its Map.Entry. In greskell, Map.Entry is expressed as GMapEntry.
• Other types are converted to themselves.

Caveat:

• Because Haskell's String is [Char], IteratorItem String returns Char, which is incorrect. Use Text if you want to deal with Strings in Gremlin.
