ToAttributes [(AttributeKey, AttributeValue)]

Defined in NetSpider.GraphML.Attribute

Methods

toAttributes :: [(AttributeKey, AttributeValue)] -> [(AttributeKey, AttributeValue)]

ToAttributes a => ToAttributes (Maybe a)

Nothing is mapped to empty attributes.

Defined in NetSpider.GraphML.Attribute

Methods

toAttributes :: Maybe a -> [(AttributeKey, AttributeValue)]

valueFromAeson :: Value -> Maybe AttributeValue

Make AttributeValue from aeson's Value. It returns Nothing, if the input is null, an object or an array. If the input is a number, the output uses AttrDouble.

attributesFromAeson :: Value -> Maybe [(AttributeKey, AttributeValue)]

Make attributes from aeson's Value. It assumes the input is an object, and its values can be converted by valueFromAeson. Otherwise, it returns Nothing.

attributesToAeson :: [(AttributeKey, AttributeValue)] -> Value

Make aeson Object as Value from attributes.
