Constructors

KeyValue :: Key a b -> Greskell b -> KeyValue a

(=:) :: Key a b -> Greskell b -> KeyValue a #

Concrete data types

Concrete data types based on Aeson data types.

Element IDs and property values are all GValue, because they are highly polymorphic. ElementID and EdgeVertexID are GValue, too.

As for properties, you can use PropertyMap and other type-classes to manipulate them.

If you want to define your own graph structure types, see README.md for detail. Basically you can use FromGraphSON instances of these concrete data types to implement parsers for your own types.

NOTE: In version 0.1.1.0 and before, these conrete data types were based on GraphSON Value. In version 0.2.0.0, this was changed to GValue, so that it can parse nested data structures encoded in GraphSON.

lookupOneValue :: (PropertyMap m, Property p) => Text -> m p v -> Maybe v #

Lookup a property value from a PropertyMap by key.

lookupListValues :: (PropertyMap m, Property p) => Text -> m p v -> [v] #

Lookup a list of property values from a PropertyMap by key.

parseOneValue :: (PropertyMap m, Property p, FromGraphSON v) => Text -> m p GValue -> Parser v #

Lookup a property GValue by the given key, and parse it.

In version 0.1.1.0 and before, this function took an argument m p (GraphSON Value). This has changed, because property types for AVertex etc have changed.

parseListValues :: (PropertyMap m, Property p, FromGraphSON v) => Text -> m p GValue -> Parser [v] #

Lookup a list of property values from a PropertyMap by the given key, and parse them.

In version 0.1.1.0 and before, this function took an argument m p (GraphSON Value). This has changed, because property types for AVertex etc have changed.

parseNonEmptyValues :: (PropertyMap m, Property p, FromGraphSON v) => Text -> m p GValue -> Parser (NonEmpty v) #

Like parseListValues, but this function fails when there is no property with the given key.

In version 0.1.1.0 and before, this function took an argument m p (GraphSON Value). This has changed, because property types for AVertex etc have changed.

fromProperties :: (PropertyMap m, Property p, Monoid (m p v)) => [p v] -> m p v #

Create a PropertyMap from list of Propertys.
