Example 72 with JsonNode

use of com.fasterxml.jackson.databind.JsonNode in project orientdb by orientechnologies.

the class OGraphSONUtility method edgeFromJson.

/**
   * Creates an edge from GraphSON using settings supplied in the constructor.
   */

    final Map<String, Object> props = OGraphSONUtility.readProperties(json, true, this.hasEmbeddedTypes);

    final JsonNode nodeLabel = json.get(GraphSONTokens._LABEL);
    // assigned an empty string edge label in cases where one does not exist. this gets around the requirement
    // that blueprints graphs have a non-null label while ensuring that GraphSON can stay flexible in parsing
    // partial bits from the JSON. Not sure if there is any gotchas developing out of this.
    final String label = nodeLabel == null ? EMPTY_STRING : nodeLabel.textValue();
    final Edge e = factory.createEdge(edgeId, out, in, label);
