Class Neo4jJSONStatement

java.lang.Object

cascading.local.tap.neo4j.Neo4jStatement<com.fasterxml.jackson.databind.JsonNode>

cascading.local.tap.neo4j.Neo4jJSONStatement

public class Neo4jJSONStatement
extends Neo4jStatement<com.fasterxml.jackson.databind.JsonNode>

Current expects a fairly shallow document.

Any child Objects (map) will be flattened into the root using the name as a prefix for the key. e.g. `tag.start` and `tag.end`.

A nested array will be handed to Neo as an Array. So far Maps nested in an Array work fine.
