This class provides a fluent builder API to help aid the configuration and instantiation of BlobClients and BlobAsyncClients, call buildClient and buildAsyncClient respectively to construct an instance of the desired client.

The following information must be provided on this builder:

  • the endpoint through .endpoint(), including the container name and blob name, in the format of https://{accountName}.blob.core.windows.net/{containerName}/{blobName}.
  • the credential through .credential() or .connectionString() if the container is not publicly accessible.

  • Constructor Details

    • BlobClientBuilder

      public BlobClientBuilder()
      Creates a builder instance that is able to configure and construct BlobClients and BlobAsyncClients.

  • Method Details

    • buildClient

      public BlobClient buildClient()
      Creates a BlobClient based on options set in the builder. BlobClients are used to perform generic blob methods such as download and get properties, use this when the blob type is unknown.

      Code Samples

    • endpoint

      public BlobClientBuilder endpoint(String endpoint)
      Sets the service endpoint, additionally parses it for information (SAS token, container name, blob name)

      If the endpoint is to a blob in the root container, this method will fail as it will interpret the blob name as the container name. With only one path element, it is impossible to distinguish between a container name and a blob in the root container, so it is assumed to be the container name as this is much more common. When working with blobs in the root container, it is best to set the endpoint to the account url and specify the blob name separately using the blobName method.

      Specified by:
      endpoint in interface com.azure.core.client.traits.EndpointTrait<BlobClientBuilder>
