recursive data structure的意思|示意

The domain model is a recursive data structure of nested objects that can be serialized as XML.

域模型是一个可以序列化为XML的嵌套对象的递归数据结构。

It is caused by recursively descending a composite data structure in such a way that, sometimes, more than one step in the descent is taken in a single recursive call.

它是由递归下行复合数据结构引起的，这种下行方式有时在一次递归调用中要下行多级。

The following figure shows the structure of an RCTE for querying recursive data.

下图显示了查询递归数据的RCTE结构。

Another difference is that, internally, the zipper version USES a linear tail-recursive traversal of the data structure instead of a recursive traversal.

另外一项差异在于，在zippers版本内部使用的是数据结构的线性尾递归遍历，而非递归遍历。
