在特定情况下有必要通过在LabVIEW列来传递多种数据类型。然而，由于该队列的LabVIEW中的限制，只有一个单独的数据类型可以通过任何特定队列传递。如果需要通过不同类型的根据情况的数据，这是一个问题。要解决这个问题的方法之一是使用一个集群，并通过传递每个迭代所有可能相关的信息，而实现这一点的优选方法是使用变体。-Driver which is good for the development of in Labview, used for queries and variants. Sometimes it is necessary to pass multiple data types through a queue in labview.　However, due to the limitations of the Queue in LabVIEW, only a single data type can be passed through any particular queue.　If you need to pass different types of data depending on the situation, this presents a problem.　A preferred way of accomplishing this is to use variants.
