BlobUtils

public BlobUtils()

方法详细资料

parseUri

public static GSBlobIdentifier parseUri(URI uri)

Parses a blob id from a Google storage uri, i.e. gs://bucket/foo/bar yields a blob with bucket name "bucket" and object name "foo/bar".

参数:

uri - The gs uri

返回:

The blob id

getTemporaryBucketName

public static String getTemporaryBucketName(GSBlobIdentifier finalBlobIdentifier,
                                            GSFileSystemOptions options)

Returns the temporary bucket name. If options specifies a temporary bucket name, we use that one; otherwise, we use the bucket name of the final blob.

参数:

finalBlobIdentifier - The final blob identifier

options - The file system options

返回:

The temporary bucket name

getTemporaryObjectPartialName

public static String getTemporaryObjectPartialName(GSBlobIdentifier finalBlobIdentifier)

Returns a temporary object partial name, i.e. .inprogress/foo/bar/ for the final blob with object name "foo/bar". The included trailing slash is deliberate, so that we can be sure that object names that start with this partial name are, in fact, temporary files associated with the upload of the associated final blob.

参数:

finalBlobIdentifier - The final blob identifier

返回:

The temporary object partial name

getTemporaryObjectName

public static String getTemporaryObjectName(GSBlobIdentifier finalBlobIdentifier,
                                            UUID temporaryObjectId)

Returns a temporary object name, formed by appending the temporary object id to the temporary object partial name, i.e. .inprogress/foo/bar/abc for the final blob with object name "foo/bar" and temporary object id "abc".

参数:

finalBlobIdentifier - The final blob identifier

temporaryObjectId - The temporary object id

返回:

The temporary object name

getTemporaryBlobIdentifier

public static GSBlobIdentifier getTemporaryBlobIdentifier(GSBlobIdentifier finalBlobIdentifier,
                                                          UUID temporaryObjectId,
                                                          GSFileSystemOptions options)

Resolves a temporary blob identifier for a provided temporary object id and the provided options.

参数:

finalBlobIdentifier - The final blob identifier

temporaryObjectId - The temporary object id

options - The file system options

返回:

The blob identifier
