Example 2 with StorageBatchResult

use of com.google.cloud.storage.StorageBatchResult in project google-cloud-java by GoogleCloudPlatform.

the class StorageSnippets method batch.

/**

    StorageBatch batch = storage.batch();
    BlobId firstBlob = BlobId.of(bucketName, blobName1);
    BlobId secondBlob = BlobId.of(bucketName, blobName2);
    batch.delete(firstBlob).notify(new BatchResult.Callback<Boolean, StorageException>() {

        public void success(Boolean result) {
        // deleted successfully
        }

        public void error(StorageException exception) {

    batch.update(BlobInfo.newBuilder(secondBlob).setContentType("text/plain").build());
    StorageBatchResult<Blob> result = batch.get(secondBlob);
    batch.submit();
    // returns get result or throws StorageException
    Blob blob = result.get();
    // [END batch]
    return blob;
