Class 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.
