Enum StorageClass

java.lang.Object

java.lang.Enum<StorageClass>

com.amazonaws.services.s3.model.StorageClass

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<StorageClass>

public enum StorageClass
extends java.lang.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.

OneZoneInfrequentAccess One Zone Infrequent Access storage class stores object data in only one Availability Zone at a lower price than STANDARD_IA.
ReducedRedundancy The reduced redundancy storage class.
Standard The default Amazon S3 storage class.
StandardInfrequentAccess Standard Infrequent Access storage class

Enum Constant Detail

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.

StandardInfrequentAccess

public static final StorageClass StandardInfrequentAccess

Standard Infrequent Access storage class

OneZoneInfrequentAccess

public static final StorageClass OneZoneInfrequentAccess

One Zone Infrequent Access storage class stores object data in only one Availability Zone at a lower price than STANDARD_IA.

IntelligentTiering

public static final StorageClass IntelligentTiering

IntelligentTiering makes it easy to lower your overall cost of storage by automatically placing data in the storage class that best matches the access patterns for the storage. With IntelligentTiering, you don’t need to define and manage individual policies for lifecycle data management or write code to transition objects between storage classes. Instead, you can use IntelligentTiering to manage transitions between Standard and S-IA without writing any application code. IntelligentTiering also manages transitions automatically to Glacier for long term archive in addition to S3 storage classes.

Method Detail

values

public static StorageClass[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

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

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static StorageClass valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

fromValue

public static StorageClass fromValue(java.lang.String s3StorageClassString)
                              throws java.lang.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.

Parameters:

s3StorageClassString - The Amazon S3 storage class ID string.

Returns:

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

Throws:

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

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Enum<StorageClass>
