Method Detail

eTag

public final String eTag()

The entity tag is an MD5 hash of that version of the object.

Returns:

The entity tag is an MD5 hash of that version of the object.

size

public final Long size()

Size in bytes of the object.

Returns:

Size in bytes of the object.

storageClass

public final ObjectVersionStorageClass storageClass()

The class of storage used to store the object.

If the service returns an enum value that is not available in the current SDK version, storageClass will return ObjectVersionStorageClass.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from storageClassAsString().

Returns:

The class of storage used to store the object.

See Also:

ObjectVersionStorageClass

storageClassAsString

public final String storageClassAsString()

The class of storage used to store the object.

If the service returns an enum value that is not available in the current SDK version, storageClass will return ObjectVersionStorageClass.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from storageClassAsString().

Returns:

The class of storage used to store the object.

ObjectVersionStorageClass

key

public final String key()

The object key.

Returns:

The object key.

versionId

public final String versionId()

Version ID of an object.

Returns:

Version ID of an object.

isLatest

public final Boolean isLatest()

Specifies whether the object is (true) or is not (false) the latest version of an object.

Returns:

Specifies whether the object is (true) or is not (false) the latest version of an object.

lastModified

public final Instant lastModified()

Date and time the object was last modified.

Returns:

Date and time the object was last modified.

owner

public final Owner owner()

Specifies the owner of the object.

Returns:

Specifies the owner of the object.

toBuilder

public ObjectVersion.Builder toBuilder()

Description copied from interface: ToCopyableBuilder

Take this object and create a builder that contains all of the current property values of this object.

Specified by:

toBuilder in interface ToCopyableBuilder<ObjectVersion.Builder,ObjectVersion>

Returns:

a builder for type T

builder

public static ObjectVersion.Builder builder()

serializableBuilderClass

public static Class<? extends ObjectVersion.Builder> serializableBuilderClass()

hashCode

public final int hashCode()

Overrides:

hashCode in class Object

equals

public final boolean equals(Object obj)

Overrides:

equals in class Object

equalsBySdkFields

public final boolean equalsBySdkFields(Object obj)

Description copied from interface: SdkPojo

Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

Specified by:

equalsBySdkFields in interface SdkPojo

Parameters:

obj - the object to be compared with

Returns:

true if the other object equals to this object by sdk fields, false otherwise.

toString

public final String toString()

Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.

Overrides:

toString in class Object

getValueForField

public final <T> Optional<T> getValueForField(String fieldName,
                                              Class<T> clazz)

sdkFields

public final List<SdkField<?>> sdkFields()

Specified by:

sdkFields in interface SdkPojo

Returns:

List of SdkField in this POJO. May be empty list but should never be null.
