构造器详细资料

COSVersionSummary

public COSVersionSummary()

方法详细资料

getBucketName

public String getBucketName()

Gets the name of the COS bucket in which this version is stored.

返回:

The name of the COS bucket in which this version is stored.

另请参阅:

setBucketName(String)

setBucketName

public void setBucketName(String bucketName)

Sets the name of the COS bucket in which this version is stored.

参数:

bucketName - The name of the COS bucket in which this version is stored.

另请参阅:

getBucketName()

getKey

public String getKey()

Gets the key under which this version is stored in COS.

返回:

The key under which this version is stored in COS.

另请参阅:

setKey(String)

setKey

public void setKey(String key)

Sets the key under which this version is stored in COS.

参数:

key - The key under which this version is stored in COS.

另请参阅:

getKey()

getVersionId

public String getVersionId()

Gets the version ID which uniquely identifies this version of an object.

Objects created before versioning was enabled or when versioning is suspended will be given the default/null version ID (see Constants#NULL_VERSION_ID). Note that the Constants#NULL_VERSION_ID is a valid version ID and is not the same as not having a version ID.

返回:

The version ID which uniquely identifies this version of an object.

另请参阅:

setVersionId(String)

setVersionId

public void setVersionId(String id)

Sets the version ID which uniquely identifies this version of an object.

参数:

id - The version ID which uniquely identifies this version of an object.

另请参阅:

getVersionId()

isLatest

public boolean isLatest()

Returns whether or not this version is the latest version for the associated object.

返回:

The value true if this version is the latest version for the associated object; returns the value false if otherwise.

setIsLatest

public void setIsLatest(boolean isLatest)

For internal use only. Sets whether this version is the latest version for the associated object. This method is intended to be used only by the client internals and developers shouldn't need to use it.

参数:

isLatest - True if this version represents the latest version for the associated object in COS.

getLastModified

public Date getLastModified()

Gets the date according to COS at which this version was last modified.

返回:

The date according to COS at which this version was last modified.

另请参阅:

setLastModified(Date)

setLastModified

public void setLastModified(Date lastModified)

Sets the date according to COS at which this version was last modified.

参数:

lastModified - The date according to COS at which this version was last modified.

另请参阅:

getLastModified()

getOwner

public Owner getOwner()

Gets the owner of this version. Returns null if the requester doesn't have Permission#ReadAcp permission for this version or owns the bucket in which it resides.

返回:

The owner of this version. Returns null if the requester doesn't have permission to see object ownership for this version.

另请参阅:

setOwner(Owner)

setOwner

public void setOwner(Owner owner)

For internal use only. Sets the owner of this version. This method is intended to be used only by the client internals and developers shouldn't need to use it.

参数:

owner - The owner of this version.

另请参阅:

getOwner()

isDeleteMarker

public boolean isDeleteMarker()

Returns whether or not this version represents a delete marker.

Delete markers are special types of versions that have no data associated with them. When deleting a versioned object in COS without specifying an explicit version ID, a new delete marker is created as the latest version of that object to mark that the object was deleted. This occurs even though the previous versions still exist in COS.

Delete markers have no data associated with them and therefore have no associated ACL, size or storage class. Only requesters with read access to a bucket can learn of their existence by listing the versions in a bucket.

返回:

The value true if this version represents a delete marker. Returns the value false if otherwise.

setIsDeleteMarker

public void setIsDeleteMarker(boolean isDeleteMarker)

Intended for internal use only in the COS client code. Sets the value of the isDeleteMarker property to record if this is a delete marker or not.

参数:

isDeleteMarker - Specify true if this version summary represents a delete marker, otherwise false if it is a regular version summary.

getETag

public String getETag()

Gets the hex encoded 128-bit MD5 hash of this version's contents as computed by COS.

返回:

The hex encoded 128-bit MD5 hash of this version's contents as computed by COS.

另请参阅:

setETag(String)

setETag

public void setETag(String eTag)

Sets the hex encoded 128-bit MD5 hash of this version's contents as computed by COS.

参数:

eTag - The hex encoded 128-bit MD5 hash of this version's contents as computed by COS.

另请参阅:
