Data.Greskell.AsIterator

Description

Since: greskell-core-0.1.2.0

Synopsis

class AsIterator a where
- type IteratorItem a

Documentation

class AsIterator a Source #

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.
