DataStructureQ[ds,type]
范例
打开所有单元 关闭所有单元基本范例 (2)
创建一个 DataStructure 对象：
ds = CreateDataStructure["Stack"]DataStructureQ[ds]一个标头为 DataStructure 但不是有效数据结构对象的表达式：
DataStructureQ[DataStructure["MyDynamicArray", {}]]
范围 (1)
创建一个 DataStructure 对象：
ds = CreateDataStructure["DynamicArray"]DataStructureQ[ds, "DynamicArray"]DataStructureQ[ds, "LinkedList"]应用 (1)
一个对 "DynamicArray" 进行原地反转的简单函数：
ArrayReverse[ds_] /; DataStructureQ[ds, "DynamicArray"] :=
Module[{start = 0, end = ds["Length"] + 1},
While[++start < --end,
ds["SwapPart", start, end]
];
ds
];ds = CreateDataStructure["DynamicArray", {9, 2, 7, 0}];
Normal[ArrayReverse[ds]]ArrayReverse[CreateDataStructure["ImmutableVector", {9, 2, 7, 0}]]
