Class BlobLeaseAsyncClient

java.lang.Object

com.azure.storage.blob.specialized.BlobLeaseAsyncClient

public final class BlobLeaseAsyncClient
extends Object

This class provides a client that contains all the leasing operations for containers and blobs. 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 this for additional ways to construct the client.

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

Method Detail

getResourceUrl

public String getResourceUrl()

Gets the URL of the lease client.

The lease will either be a container or blob URL depending on which the lease client is associated.

Returns:

URL of the lease client.

getLeaseId

public String getLeaseId()

Get the lease ID for this lease.

Returns:

the lease ID.

acquireLease

public Mono<String> acquireLease(int duration)

Acquires a lease for write and delete operations. The lease duration must be between 15 to 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:

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

Returns:

A reactive response containing the lease ID.

acquireLeaseWithResponse

public Mono<Response<String>> acquireLeaseWithResponse(int duration,
                                                       RequestConditions modifiedAccessConditions)

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

Code Samples

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

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

Parameters:

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

modifiedAccessConditions - 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.

renewLease

public Mono<String> renewLease()

Renews the previously acquired lease.

Code Samples

client.renewLease().subscribe(response -> System.out.printf("Renewed lease ID is %s%n", response));

Returns:

A reactive response containing the renewed lease ID.

renewLeaseWithResponse

public Mono<Response<String>> renewLeaseWithResponse(RequestConditions modifiedAccessConditions)

Renews the previously acquired lease.

Code Samples

RequestConditions modifiedAccessConditions = new RequestConditions()
    .setIfUnmodifiedSince(OffsetDateTime.now().minusDays(3));

client.renewLeaseWithResponse(modifiedAccessConditions).subscribe(response ->
    System.out.printf("Renewed lease ID is %s%n", response.getValue()));

Parameters:

modifiedAccessConditions - 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 renewed lease ID.

releaseLease

public Mono<Void> releaseLease()

Releases the previously acquired lease.

Code Samples

client.releaseLease().subscribe(response -> System.out.println("Completed release lease"));

Returns:

A reactive response signalling completion.

releaseLeaseWithResponse

public Mono<Response<Void>> releaseLeaseWithResponse(RequestConditions modifiedAccessConditions)

Releases the previously acquired lease.

Code Samples

RequestConditions modifiedAccessConditions = new RequestConditions()
    .setIfUnmodifiedSince(OffsetDateTime.now().minusDays(3));

client.releaseLeaseWithResponse(modifiedAccessConditions).subscribe(response ->
    System.out.printf("Release lease completed with status %d%n", response.getStatusCode()));

Parameters:

modifiedAccessConditions - 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 signalling completion.

breakLease

public Mono<Integer> 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<Response<Integer>> breakLeaseWithResponse(Integer breakPeriodInSeconds,
                                                      RequestConditions modifiedAccessConditions)

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 modifiedAccessConditions = new RequestConditions()
    .setIfUnmodifiedSince(OffsetDateTime.now().minusDays(3));

client.breakLeaseWithResponse(retainLeaseInSeconds, modifiedAccessConditions).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.

modifiedAccessConditions - 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.

changeLease

public Mono<String> changeLease(String proposedId)

Changes the lease ID.

Code Samples

client.changeLease("proposedId").subscribe(response -> System.out.printf("Changed lease ID is %s%n", response));

Parameters:

proposedId - A new lease ID in a valid GUID format.

Returns:

A reactive response containing the new lease ID.

changeLeaseWithResponse

public Mono<Response<String>> changeLeaseWithResponse(String proposedId,
                                                      RequestConditions modifiedAccessConditions)

Changes the lease ID.

RequestConditions modifiedAccessConditions = new RequestConditions()
    .setIfUnmodifiedSince(OffsetDateTime.now().minusDays(3));

client.changeLeaseWithResponse("proposedId", modifiedAccessConditions).subscribe(response ->
    System.out.printf("Changed lease ID is %s%n", response.getValue()));

Parameters:

proposedId - A new lease ID in a valid GUID format.

modifiedAccessConditions - 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 new lease ID.

getAccountName

public String getAccountName()

Get associated account name.

Returns:

account name associated with this storage resource.
