NetSpider.GraphML.Writer

This module defines tools to serialize a SnapshotGraph into GraphML format.

Since: 0.3.1.0

Functions

writeGraphML :: (ToNodeID n, ToAttributes na, ToAttributes la) => SnapshotGraph n na la -> Text

writeGraphMLWith the default options.

writeGraphMLWith :: (ToNodeID n, ToAttributes na, ToAttributes la) => WriteOption -> SnapshotGraph n na la -> Text

Show the SnapshotGraph into GraphML format. WriteOption controls the conversion.

Options

data WriteOption

Options to write GraphML. Use defWriteOption to get the default values.

woptDefaultDirected :: WriteOption -> Bool

If True, set GraphML's edgedefault attribute to directed. If False, set it to undirected. Note that regardless of this option, each edge element specifies directed attribute explicitly.

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.
