Changes a blob's metadata. The specified metadata in this method will replace existing metadata. If old values must be preserved, they must be downloaded and included in the call to this method.

Code Samples

BlobRequestConditions accessConditions = new BlobRequestConditions().setLeaseId(leaseId);

System.out.printf("Set metadata completed with status %d%n",
    client.setMetadataWithResponse(Collections.singletonMap("metadata", "value"), accessConditions, timeout,
        new Context(key1, value1)).getStatusCode());

For more information, see the Azure Docs

Parameters:

metadata - Metadata to associate with the blob.

accessConditions - BlobRequestConditions

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:

A response containing status code and HTTP headers.

createSnapshot

public BlobClientBase createSnapshot()

Creates a read-only snapshot of the blob.

Code Samples

System.out.printf("Identifier for the snapshot is %s%n", client.createSnapshot().getSnapshotId());

For more information, see the Azure Docs

Returns:

A response containing a BlobClient which is used to interact with the created snapshot, use BlobClientBase.getSnapshotId() to get the identifier for the snapshot.

createSnapshotWithResponse

public Response<BlobClientBase> createSnapshotWithResponse(Map<String,String> metadata,
                                                           BlobRequestConditions accessConditions,

Creates a read-only snapshot of the blob.

Code Samples

Map<String, String> snapshotMetadata = Collections.singletonMap("metadata", "value");
BlobRequestConditions accessConditions = new BlobRequestConditions().setLeaseId(leaseId);

System.out.printf("Identifier for the snapshot is %s%n",
    client.createSnapshotWithResponse(snapshotMetadata, accessConditions, timeout,
        new Context(key1, value1)).getValue());

For more information, see the Azure Docs

Parameters:

metadata - Metadata to associate with the blob snapshot.

accessConditions - BlobRequestConditions

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:

A response containing a BlobClient which is used to interact with the created snapshot, use BlobClientBase.getSnapshotId() to get the identifier for the snapshot.

setAccessTier

public void setAccessTier(AccessTier tier)

Sets the tier on a blob. The operation is allowed on a page blob in a premium storage account or a block blob in a blob storage or GPV2 account. A premium page blob's tier determines the allowed size, IOPS, and bandwidth of the blob. A block blob's tier determines the Hot/Cool/Archive storage type. This does not update the blob's etag.

Code Samples

client.setAccessTier(AccessTier.HOT);
System.out.println("Set tier completed.");

For more information, see the Azure Docs

Parameters:

tier - The new tier for the blob.

setAccessTierWithResponse

public Response<Void> setAccessTierWithResponse(AccessTier tier,
                                                RehydratePriority priority,
                                                String leaseId,
                                                Duration timeout,
                                                Context context)

Sets the tier on a blob. The operation is allowed on a page blob in a premium storage account or a block blob in a blob storage or GPV2 account. A premium page blob's tier determines the allowed size, IOPS, and bandwidth of the blob. A block blob's tier determines the Hot/Cool/Archive storage type. This does not update the blob's etag.

Code Samples

System.out.printf("Set tier completed with status code %d%n",
    client.setAccessTierWithResponse(AccessTier.HOT, RehydratePriority.STANDARD, leaseId, timeout,
        new Context(key2, value2)).getStatusCode());

For more information, see the Azure Docs

Parameters:

tier - The new tier for the blob.

priority - Optional priority to set for re-hydrating blobs.

leaseId - The lease ID the active lease on the blob must match.

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:

A response containing status code and HTTP headers.
