枚举 StorageClass

java.lang.Object

java.lang.Enum<StorageClass>

com.sinacloud.scs.services.scs.model.StorageClass

所有已实现的接口:

Serializable, Comparable<StorageClass>

public enum StorageClass
extends Enum<StorageClass>

Specifies constants that define Amazon S3 storage classes. The standard storage class is the default storage class.

Amazon S3 offers multiple storage classes for different customers' needs. The STANDARD storage class is the default storage class, and means that redundant copies of data will be stored in different locations.

The REDUCED_REDUNDANCY storage class offers customers who are using Amazon S3 for storing non-critical, reproducible data a low-cost highly available, but less redundant, storage option.

枚举常量详细资料

Standard

public static final StorageClass Standard

The default Amazon S3 storage class. This storage class is recommended for critical, non-reproducible data. The standard storage class is a highly available and highly redundant storage option provided for an affordable price.

ReducedRedundancy

public static final StorageClass ReducedRedundancy

The reduced redundancy storage class. This storage class allows customers to reduce their storage costs in return for a reduced level of data redundancy. Customers who are using Amazon S3 for storing non-critical, reproducible data can choose this low cost and highly available, but less redundant, storage option.

Glacier

public static final StorageClass Glacier

The Amazon Glacier storage class. This storage class means your object's data is stored in Amazon Glacier, and Amazon S3 stores a reference to the data in the Amazon S3 bucket.

方法详细资料

values

public static StorageClass[] 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 (StorageClass c : StorageClass.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 StorageClass 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

fromValue

public static StorageClass fromValue(String s3StorageClassString)
                              throws IllegalArgumentException

Returns the Amazon S3 StorageClass enumeration value representing the specified Amazon S3 StorageClass ID string. If the specified string doesn't map to a known Amazon S3 storage class, an IllegalArgumentException is thrown.

参数:

s3StorageClassString - The Amazon S3 storage class ID string.

返回:

The Amazon S3 StorageClass enumeration value representing the specified Amazon S3 storage class ID.

抛出:

IllegalArgumentException - If the specified value does not map to one of the known Amazon S3 storage classes.

toString

public String toString()

覆盖:

toString 在类中 Enum<StorageClass>
