Attributes classes

class NodeAttributes ps where

Class of user-defined types for node attributes. Its content is stored in the NetSpider database.

Methods

writeNodeAttributes :: ps -> Binder (Walk SideEffect (VFoundNode ps) (VFoundNode ps))

Return Walk to write the attributes to the VFoundNode.

parseNodeAttributes :: PropertyMapList AVertexProperty GValue -> Parser ps

Parse the vertex proprerties into the attributes.

Instances

NodeAttributes ()

No attributes.

Defined in NetSpider.Graph.Internal

Methods

writeNodeAttributes :: () -> Binder (Walk SideEffect (VFoundNode ()) (VFoundNode ()))

parseNodeAttributes :: PropertyMapList AVertexProperty GValue -> Parser ()

(FromGraphSON v, ToJSON v) => NodeAttributes (PropertyMapList AVertexProperty v)

Straightforward implementation. Note that writeNodeAttributes does not write meta-properties of the AVertexProperty.
