Parameters:

Returns:

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:

public Response 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:

Returns:

public Response setAccessTierWithResponse(BlobSetAccessTierOptions options, 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(new BlobSetAccessTierOptions(AccessTier.HOT)
         .setPriority(RehydratePriority.STANDARD)
         .setLeaseId(leaseId)
         .setTagsConditions(tags),
         timeout, new Context(key2, value2)).getStatusCode());

Parameters:

Returns:

public void setHttpHeaders(BlobHttpHeaders headers)

Changes a blob's HTTP header properties. if only one HTTP header is updated, the others will all be erased. In order to preserve existing values, they must be passed alongside the header being changed.

Code Samples

client.setHttpHeaders(new BlobHttpHeaders()
     .setContentLanguage("en-US")
     .setContentType("binary"));
 System.out.println("Set HTTP headers completed");

For more information, see the Azure Docs

Parameters:

public Response setHttpHeadersWithResponse(BlobHttpHeaders headers, BlobRequestConditions requestConditions, Duration timeout, Context context)

Changes a blob's HTTP header properties. if only one HTTP header is updated, the others will all be erased. In order to preserve existing values, they must be passed alongside the header being changed.

Code Samples

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

 System.out.printf("Set HTTP headers completed with status %d%n",
     client.setHttpHeadersWithResponse(new BlobHttpHeaders()
         .setContentLanguage("en-US")
         .setContentType("binary"), requestConditions, timeout, new Context(key1, value1))
         .getStatusCode());

Parameters:

Returns:

public BlobImmutabilityPolicy setImmutabilityPolicy(BlobImmutabilityPolicy immutabilityPolicy)

Sets the immutability policy on a blob, blob snapshot or blob version.

NOTE: Blob Versioning must be enabled on your storage account and the blob must be in a container with immutable storage with versioning enabled to call this API.

Code Samples

BlobImmutabilityPolicy policy = new BlobImmutabilityPolicy()
     .setPolicyMode(BlobImmutabilityPolicyMode.LOCKED)
     .setExpiryTime(OffsetDateTime.now().plusDays(1));
 BlobImmutabilityPolicy setPolicy = client.setImmutabilityPolicy(policy);
 System.out.println("Successfully completed setting the immutability policy");

Parameters:

Returns:

public Response setImmutabilityPolicyWithResponse(BlobImmutabilityPolicy immutabilityPolicy, BlobRequestConditions requestConditions, Duration timeout, Context context)

Sets the immutability policy on a blob, blob snapshot or blob version.

NOTE: Blob Versioning must be enabled on your storage account and the blob must be in a container with immutable storage with versioning enabled to call this API.

Code Samples

BlobImmutabilityPolicy immutabilityPolicy = new BlobImmutabilityPolicy()
     .setPolicyMode(BlobImmutabilityPolicyMode.LOCKED)
     .setExpiryTime(OffsetDateTime.now().plusDays(1));
 BlobRequestConditions requestConditions = new BlobRequestConditions()
     .setIfUnmodifiedSince(OffsetDateTime.now().minusDays(1));
 Response<BlobImmutabilityPolicy> response = client.setImmutabilityPolicyWithResponse(immutabilityPolicy,
     requestConditions, timeout, new Context(key1, value1));
 System.out.println("Successfully completed setting the immutability policy");

Parameters:

Returns:

public BlobLegalHoldResult setLegalHold(boolean legalHold)

Sets a legal hold on the blob.

NOTE: Blob Versioning must be enabled on your storage account and the blob must be in a container with immutable storage with versioning enabled to call this API.
