Question

我正在尝试在titan中创建关系，并试图在创建时给出一个包含属性的数组。

while (startNode.hasNext())
        {
            Vertex tempVertex = startNode.next();
            while (endNode.hasNext())
            {
                tempVertex.addEdge(storage.getId(), endNode.next(), keyValue);
            }
        }

但它在边缘创建上抛出了以下错误。

int i = 0;
        for (Map.Entry<String, Object> entry : storage.getProperties().entrySet())
        {
            keyValue[i] = entry.getKey();
            keyValue[i + 1] = entry.getValue();
            i += 2;
        }

通常情况下，地图应该在每个偶数索引处都有字符串。

Titan - java.lang.IllegalArgumentException - 创建关系
