BlobContainerClient Class

Definition

Client to a container. It may only be instantiated through a BlobContainerClientBuilder or via the method getBlobContainerClient(String containerName). This class does not hold any state about a particular container but is instead a convenient way of sending off appropriate requests to the resource on the service. It may also be used to construct URLs to blobs.

This client contains operations on a container. Operations on a blob are available on BlobClient through getBlobClient(String blobName), and operations on the service are available on BlobServiceClient.

Please refer to the Azure Docs for more information on containers.

Methods

create()

Creates a new container within a storage account. If a container with the same name already exists, the operation fails. For more information, see the Azure Docs.

Code Samples

{@codesnippet com.azure.storage.blob.BlobContainerClient.create}

createWithResponse(Map<String,String> metadata, PublicAccessType accessType, Duration timeout, Context context)

Creates a new container within a storage account. If a container with the same name already exists, the operation fails. For more information, see the Azure Docs.

Code Samples

{@codesnippet com.azure.storage.blob.BlobContainerClient.createWithResponse#Map-PublicAccessType-Duration-Context}

delete()

Marks the specified container for deletion. The container and any blobs contained within it are later deleted during garbage collection. For more information, see the Azure Docs.

Code Samples

{@codesnippet com.azure.storage.blob.BlobContainerClient.delete}

deleteWithResponse(BlobRequestConditions requestConditions, Duration timeout, Context context)

Marks the specified container for deletion. The container and any blobs contained within it are later deleted during garbage collection. For more information, see the Azure Docs.

Code Samples

{@codesnippet com.azure.storage.blob.BlobContainerClient.deleteWithResponse#BlobRequestConditions-Duration-Context}

exists()

Gets if the container this client represents exists in the cloud.

Gets the URL of the container represented by this client.

getBlobVersionClient(String blobName, String versionId)

Initializes a new BlobClient object by concatenating blobName to the end of ContainerAsyncClient's URL. The new BlobClient uses the same request policy pipeline as the ContainerAsyncClient.

getCustomerProvidedKey()
