基本范例  (2)

移除本地对象：

Wolfram Language code: Put[0, LocalObject["zero"]]
Wolfram Language code: DeleteObject[LocalObject["zero"]]

创建本地对象：

Wolfram Language code: l = Put[0, LocalObject["zero"]]

创建云对象：

Wolfram Language code: c = CloudPut[0, CloudObject["zero"]]

同时删除两个对象：

Wolfram Language code: DeleteObject[{l, c}]

范围  (12)

移除持久性对象：

Wolfram Language code: PersistentSymbol["one", "KernelSession"] = 1;
Wolfram Language code: DeleteObject[PersistentObject["one", "KernelSession"]]

移除所有 $ContextPath 有给定键的持久性对象：

Wolfram Language code: DeleteObject[PersistentObjects["one"]]

移除给定永久位置的所有永久性对象：

Wolfram Language code: DeleteObject[PersistenceLocation["KernelSession"]]

创建云对象：

Wolfram Language code: CloudPut[42, CloudObject["answer"]]

删除云对象：

Wolfram Language code: DeleteObject[CloudObject["answer"]]

创建目录云对象：

Wolfram Language code: dir = CreateDirectory[CloudObject["answers"]]

添加内容到目录中：

Wolfram Language code: CloudPut[42, FileNameJoin[{dir, "problem1"}]]

删除目录云对象及其内容：

Wolfram Language code: DeleteObject[dir]

移除信道对象：

Wolfram Language code: channel = CreateChannel[]
Wolfram Language code: DeleteObject[channel]

永久删除数据仓：

Wolfram Language code: bin = CreateDatabin[]
Wolfram Language code: DeleteObject[bin]

创建、缓存并使用一个数据资源对象：

Wolfram Language code: resource = ResourceObject[<|"ResourceType" -> "Data", "Name" -> "Divisors of 2^20", "Content" -> Divisors[2 ^ 20]|>]
Wolfram Language code: LocalCache[resource]
Wolfram Language code: ResourceData[resource]

删除资源：

Wolfram Language code: DeleteObject[resource]

从公共数据库取回资源：

Wolfram Language code: resource = ResourceObject["Fireballs and Bolides"]

删除资源在本地的缓存：

Wolfram Language code: DeleteObject[resource]

开启一个外部会话：

Wolfram Language code: session = StartExternalSession["Python"]

停止会话：

Wolfram Language code: DeleteObject[session]

开始监听一个可用的套接口，对事件应用处理函数：

Wolfram Language code: listener = SocketListen[Automatic, Print]

终止会话：

Wolfram Language code: DeleteObject[listener]

创建并移除一个权限群：

Wolfram Language code: CreatePermissionsGroup["TigerTeam", {$CloudUserID, "user@wolfram.com"}]
Wolfram Language code: DeleteObject[PermissionsGroup["TigerTeam"]]

从使用它们的云对象中删除权限密码：

Wolfram Language code: CloudDeploy[Delayed[RandomInteger[2 ^ 128]], Permissions -> PermissionsKey["altkey"] -> "Execute"]
Wolfram Language code: DeleteObject[PermissionsKey["altkey"]]

删除远程批处理任务：

Wolfram Language code: job = RemoteBatchSubmit["WolframBatch", FactorInteger[2 ^ 1023 - 7]]
Wolfram Language code: DeleteObject[job]

用 Once 进行某种形式的动态编程，同时用自定义位置缓存算出的值：

Wolfram Language code: fib[0] = 0;fib[1] = 1; fib[n_] := Once[fib[n - 1] + fib[n - 2], "KernelSession" -> "fib"];
Wolfram Language code: Timing[Block[{$RecursionLimit = ∞}, res = fib[6000]];N[res]]

求生成的缓存的值的数量：

Wolfram Language code: Length[PersistentObjects[All, "KernelSession" -> "fib"]]

通过删除自定义持久性位置，在重做计时实验之前删除缓存的值:

Wolfram Language code: DeleteObject[PersistenceLocation["KernelSession" -> "fib"]]

属性和关系  (3)

用 Remove 移除符号和本地符号：

Wolfram Language code: symbol = LocalSymbol["mysym"] = 0;
Wolfram Language code: Remove[symbol]
Wolfram Language code: Remove[LocalSymbol["mysym"]]

用 DeleteFile 删除文件：

Wolfram Language code: file = FileNameJoin[{CreateDirectory[], "test."}]
Wolfram Language code: Put[0, file]
Wolfram Language code: DeleteFile[file]

与 DeleteDirectory 的默认行为不同，即使云目录含有其他对象，DeleteObject 还是会将其删除：

Wolfram Language code: CloudPut[42, CloudObject["mydir/myfile"]]
Wolfram Language code: DeleteDirectory[CloudObject["mydir"]]
Wolfram Language code: DeleteObject[CloudObject["mydir"]]
Wolfram Language code: DirectoryQ[CloudObject["mydir"]]
