queryCompletedResumableUpload

com.google.api.services.storage.model.StorageObject queryCompletedResumableUpload(String uploadId,

Attempts to retrieve the StorageObject from a completed resumable upload. When a resumable upload completes, the response will be the up-to-date StorageObject metadata. This up-to-date metadata can then be used to validate the total size of the object along with new generation and other information.

If for any reason, the response to the final PUT to a resumable upload is not received, this method can be used to query for the up-to-date StorageObject. If the upload is complete, this method can be used to access the StorageObject independently from any other liveness or conditional criteria requirements that are otherwise applicable when using get(StorageObject, Map).

Parameters:

uploadId - resumable upload ID URL

totalBytes - the total number of bytes that should have been written.

Throws:

StorageException - if the upload is incomplete or does not exist

Parameters:

uploadId - resumable upload ID

toWrite - a portion of the content

toWriteOffset - starting position in the toWrite array

destOffset - starting position in the destination data

length - the number of bytes to be uploaded

last - true, if toWrite is the final content portion
