BlockBlobClient Class | Microsoft Learn

public final class BlockBlobClient
extends BlobClientBase

Client to a block blob. It may only be instantiated through a SpecializedBlobClientBuilder or via the method getBlockBlobClient(). This class does not hold any state about a particular blob, but is instead a convenient way of sending appropriate requests to the resource on the service.

Please refer to the Azure Docs for more information.

public BlockBlobItem commitBlockList(List<String> base64BlockIds)

Writes a blob by specifying the list of block IDs that are to make up the blob. In order to be written as part of a blob, a block must have been successfully written to the server in a prior stageBlock operation.

Any blocks not specified in the block list and permanently deleted. For more information, see the Azure Docs.

Parameters:

timeout - An optional timeout value beyond which a RuntimeException will be raised.

context - Additional context that is passed through the Http pipeline during the service call.

Returns:

The information of the uploaded block blob.

public Response<BlockBlobItem> uploadWithResponse(InputStream data, long length, BlobHttpHeaders headers, Map<String,String> metadata, AccessTier tier, byte[] contentMd5, BlobRequestConditions requestConditions, Duration timeout, Context context)

Creates a new block blob, or updates the content of an existing block blob. Updating an existing block blob overwrites any existing metadata on the blob. Partial updates are not supported with PutBlob; the content of the existing blob is overwritten with the new content. To perform a partial update of a block blob's, use PutBlock and PutBlockList. For more information, see the Azure Docs.

To avoid overwriting, pass "*" to setIfNoneMatch(String ifNoneMatch).

Code Samples

BlobHttpHeaders headers = new BlobHttpHeaders()
     .setContentMd5(MessageDigest.getInstance("MD5").digest("data".getBytes(StandardCharsets.UTF_8)))
     .setContentLanguage("en-US")
     .setContentType("binary");

 Map<String, String> metadata = Collections.singletonMap("metadata", "value");

 byte[] md5 = MessageDigest.getInstance("MD5").digest("data".getBytes(StandardCharsets.UTF_8));

 BlobRequestConditions requestConditions = new BlobRequestConditions()
     .setLeaseId(leaseId)
     .setIfUnmodifiedSince(OffsetDateTime.now().minusDays(3));
 Context context = new Context("key", "value");

 System.out.printf("Uploaded BlockBlob MD5 is %s%n", Base64.getEncoder()
     .encodeToString(client.uploadWithResponse(data, length, headers, metadata, AccessTier.HOT, md5,
         requestConditions, timeout, context)
         .getValue()
         .getContentMd5()));

Parameters:

- The data to write to the blob. The data must be markable. This is in order to support retries. If the data is not markable, consider using

and writing to the returned OutputStream. Alternatively, consider wrapping your data source in a

to add mark support.

length - The exact length of the data. It is important that this value match precisely the length of the data provided in the InputStream.

metadata - Metadata to associate with the blob. If there is leading or trailing whitespace in any metadata key or value, it must be removed or encoded.

contentMd5 - An MD5 hash of the block content. This hash is used to verify the integrity of the block during transport. When this header is specified, the storage service compares the hash of the content that has arrived with this header value. Note that this MD5 hash is not stored with the blob. If the two hashes do not match, the operation will fail.

timeout - An optional timeout value beyond which a RuntimeException will be raised.

context - Additional context that is passed through the Http pipeline during the service call.

Returns:

The information of the uploaded block blob.
