public final class BlobLeaseAsyncClient

This class provides a client that contains all the leasing operations for BlobContainerAsyncClient and BlobAsyncClient. This client acts as a supplement to those clients and only handles leasing operations.

Instantiating a BlobLeaseAsyncClient

BlobLeaseAsyncClient blobLeaseAsyncClient = new BlobLeaseClientBuilder()
     .blobAsyncClient(blobAsyncClient)
     .buildAsyncClient();

BlobLeaseAsyncClient blobLeaseAsyncClient = new BlobLeaseClientBuilder()
     .containerAsyncClient(blobContainerAsyncClient)
     .buildAsyncClient();

View BlobLeaseClientBuilder for additional ways to construct the client.

For more information about leasing see the container leasing or blob leasing documentation.

Method Details

acquireLease

public Mono acquireLease(int durationInSeconds)

Acquires a lease for write and delete operations. The lease duration must be between 15 and 60 seconds or -1 for an infinite duration.

Code Samples

client.acquireLease(60).subscribe(response -> System.out.printf("Lease ID is %s%n", response));

Parameters:

durationInSeconds - The duration of the lease between 15 and 60 seconds or -1 for an infinite duration.

Returns:

A reactive response containing the lease ID.

acquireLeaseWithResponse

public Mono> acquireLeaseWithResponse(BlobAcquireLeaseOptions options)

Acquires a lease for write and delete operations. The lease duration must be between 15 and 60 seconds, or -1 for an infinite duration.

Code Samples

BlobLeaseRequestConditions requestConditions = new BlobLeaseRequestConditions()
     .setIfModifiedSince(OffsetDateTime.now().minusDays(3));

 BlobAcquireLeaseOptions options = new BlobAcquireLeaseOptions(60)
     .setRequestConditions(requestConditions);

 client.acquireLeaseWithResponse(options).subscribe(response ->
     System.out.printf("Lease ID is %s%n", response.getValue()));

Parameters:

options - BlobAcquireLeaseOptions

Returns:

A reactive response containing the lease ID.

acquireLeaseWithResponse

public Mono> acquireLeaseWithResponse(int durationInSeconds, RequestConditions modifiedRequestConditions)

Acquires a lease for write and delete operations. The lease duration must be between 15 and 60 seconds, or -1 for an infinite duration.

Code Samples

RequestConditions modifiedRequestConditions = new RequestConditions()
     .setIfModifiedSince(OffsetDateTime.now().minusDays(3));

 client.acquireLeaseWithResponse(60, modifiedRequestConditions).subscribe(response ->
     System.out.printf("Lease ID is %s%n", response.getValue()));

Parameters:

durationInSeconds - The duration of the lease between 15 and 60 seconds or -1 for an infinite duration.

modifiedRequestConditions - Standard HTTP Access conditions related to the modification of data. ETag and LastModifiedTime are used to construct conditions related to when the resource was changed relative to the given request. The request will fail if the specified condition is not satisfied.

Returns:

A reactive response containing the lease ID.

breakLease

public Mono breakLease()

Breaks the previously acquired lease, if it exists.

Code Samples

client.breakLease().subscribe(response ->
     System.out.printf("The broken lease has %d seconds remaining on the lease", response));

Returns:

A reactive response containing the remaining time in the broken lease in seconds.

breakLeaseWithResponse

public Mono> breakLeaseWithResponse(BlobBreakLeaseOptions options)

Breaks the previously acquired lease, if it exists.

If null is passed for breakPeriodInSeconds a fixed duration lease will break after the remaining lease period elapses and an infinite lease will break immediately.

Code Samples

Integer retainLeaseInSeconds = 5;
 BlobLeaseRequestConditions requestConditions = new BlobLeaseRequestConditions()
     .setIfUnmodifiedSince(OffsetDateTime.now().minusDays(3));

 BlobBreakLeaseOptions options = new BlobBreakLeaseOptions()
     .setBreakPeriod(Duration.ofSeconds(retainLeaseInSeconds))
     .setRequestConditions(requestConditions);

 client.breakLeaseWithResponse(options).subscribe(response ->
     System.out.printf("The broken lease has %d seconds remaining on the lease", response.getValue()));

Parameters:

options - BlobBreakLeaseOptions

Returns:

A reactive response containing the remaining time in the broken lease in seconds.

breakLeaseWithResponse

public Mono> breakLeaseWithResponse(Integer breakPeriodInSeconds, RequestConditions modifiedRequestConditions)

Breaks the previously acquired lease, if it exists.

If null is passed for breakPeriodInSeconds a fixed duration lease will break after the remaining lease period elapses and an infinite lease will break immediately.

Code Samples

Integer retainLeaseInSeconds = 5;
 RequestConditions modifiedRequestConditions = new RequestConditions()
     .setIfUnmodifiedSince(OffsetDateTime.now().minusDays(3));

 client.breakLeaseWithResponse(retainLeaseInSeconds, modifiedRequestConditions).subscribe(response ->
     System.out.printf("The broken lease has %d seconds remaining on the lease", response.getValue()));

Parameters:

breakPeriodInSeconds - An optional duration, between 0 and 60 seconds, that the lease should continue before it is broken. If the break period is longer than the time remaining on the lease the remaining time on the lease is used. A new lease will not be available before the break period has expired, but the lease may be held for longer than the break period.

modifiedRequestConditions - Standard HTTP Access conditions related to the modification of data. ETag and LastModifiedTime are used to construct conditions related to when the resource was changed relative to the given request. The request will fail if the specified condition is not satisfied.

Returns:

A reactive response containing the remaining time in the broken lease in seconds.
