Graph.prepareVertex介绍

[英]Prepare a vertex to be added to the graph. This method provides a way to build up a vertex with it's properties to be inserted with a single operation. The id of the new vertex will be generated using an IdGenerator.
[中]准备要添加到图形的顶点。此方法提供了一种通过单个操作插入顶点的属性来构建顶点的方法。新顶点的id将使用IdGenerator生成。

private VertexBuilder prepareVertex(String prefix, String iri, String workspaceId, Visibility visibility, VisibilityJson visibilityJson) {
  if (isPublic(workspaceId)) {
    return graph.prepareVertex(prefix + iri, visibility);
  }
  String id = prefix + Hashing.sha1().hashString(workspaceId + iri, Charsets.UTF_8).toString();
  visibilityJson.addWorkspace(workspaceId);
  return graph.prepareVertex(id, visibilityTranslator.toVisibility(visibilityJson).getVisibility());
}
