枚举 CryptoStorageMode

java.lang.Object

java.lang.Enum<CryptoStorageMode>

com.ksyun.ks3.service.encryption.model.CryptoStorageMode

所有已实现的接口:

Serializable, Comparable<CryptoStorageMode>

public enum CryptoStorageMode
extends Enum<CryptoStorageMode>

Denotes the different storage modes available for storing the encryption information that accompanies encrypted objects in S3. The encryption information includes an encrypted envelope symmetric key, an initialization vector, and a description of the encryption materials used during encryption.

ObjectMetadata is the default storage mode. If the ObjectMetadata mode is used, then encryption information will be placed in the metadata of the encrypted object stored in S3. Note: There is a 2 KB limit on the size of the metadata, so be careful that you do not run out of space if you are storing a lot of your own metadata.

If the InstructionFile mode is used, then encryption information will be placed in a separate instruction file that will be stored in the same bucket as the encrypted object in S3. No metadata will be used for storing encryption information.

方法详细资料

values

public static CryptoStorageMode[] values()

按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示:

for (CryptoStorageMode c : CryptoStorageMode.values())
    System.out.println(c);

返回:

按照声明该枚举类型的常量的顺序返回的包含这些常量的数组

valueOf

public static CryptoStorageMode valueOf(String name)

返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量

NullPointerException - 如果参数为空值
