Class StorageBatch (2.19.0)

A batch of operations to be submitted to Google Cloud Storage using a single RPC request.

Example of using a batch request to delete, update and get a blob:

 StorageBatch batch = storage.batch();
 BlobId firstBlob = BlobId.of("bucket", "blob1"));
 BlobId secondBlob = BlobId.of("bucket", "blob2"));
 batch.delete(firstBlob).notify(new BatchResult.Callback<Boolean, StorageException>() {
   public void success(Boolean result) {
     // deleted successfully
   }

   public void error(StorageException exception) {
     // delete failed
   }
 });
 batch.update(BlobInfo.builder(secondBlob).contentType("text/plain").build());
 StorageBatchResult<Blob> result = batch.get(secondBlob);
 batch.submit();
 Blob blob = result.get(); // returns get result or throws StorageException
 

Adds a request representing the "delete blob" operation to this batch. Calling StorageBatchResult#get() on the return value yields true upon successful deletion, false if the blob was not found, or throws a StorageException if the operation failed.

Adds a request representing the "delete blob" operation to this batch. Calling StorageBatchResult#get() on the return value yields true upon successful deletion, false if the blob was not found, or throws a StorageException if the operation failed.

Adds a request representing the "get blob" operation to this batch. The options can be used in the same way as for Storage#get(BlobId, BlobGetOption...). Calling StorageBatchResult#get() on the return value yields the requested Blob if successful, null if no such blob exists, or throws a StorageException if the operation failed.

Adds a request representing the "get blob" operation to this batch. The options can be used in the same way as for Storage#get(BlobId, BlobGetOption...). Calling StorageBatchResult#get() on the return value yields the requested Blob if successful, null if no such blob exists, or throws a StorageException if the operation failed.

Submits this batch for processing using a single RPC request.

Adds a request representing the "update blob" operation to this batch. The options can be used in the same way as for Storage#update(BlobInfo, BlobTargetOption...). Calling StorageBatchResult#get() on the return value yields the updated Blob if successful, or throws a StorageException if the operation failed.
