postorder traversal meaning in English
后序遍历
Examples
- Nevertheless , some indices do not contain all element nodes , many paths need to still be examined in the query ; other indices produce redundant data in the preorder or postorder traversal , this makes the cost of query much more
然而有的索引不包含所有的元素结点，因而在进行查询时许多路径仍需要检测；有的在向前或向后遍历时产生了大量的冗余数据，从而造成查询代价较大。
