public class StorageBatch extends Object
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
