java.lang.Object

com.microsoft.azure.storage.blob.StorageURL

com.microsoft.azure.storage.blob.BlobURL

com.microsoft.azure.storage.blob.AppendBlobURL

public final class AppendBlobURL
extends BlobURL

Represents a URL to an append blob. It may be obtained by direct construction or via the create method on a ContainerURL object. This class does not hold any state about a particular append blob but is instead a convenient way of sending off appropriate requests to the resource on the service. Please refer to the Azure Docs

Constructor Detail

AppendBlobURL

public AppendBlobURL(URL url,
                     com.microsoft.rest.v2.http.HttpPipeline pipeline)

Creates a AppendBlobURL object pointing to the account specified by the URL and using the provided pipeline to make HTTP requests.

Parameters:

url - A URL to an Azure Storage append blob.

pipeline - A HttpPipeline which configures the behavior of HTTP exchanges. Please refer to the createPipeline method on StorageURL for more information.

Method Detail

withPipeline

public AppendBlobURL withPipeline(com.microsoft.rest.v2.http.HttpPipeline pipeline)

Creates a new AppendBlobURL with the given pipeline.

Overrides:

withPipeline in class BlobURL

Parameters:

pipeline - An HttpPipeline object to process HTTP transactions.

Returns:

An AppendBlobURL object with the given pipeline.

withSnapshot

public AppendBlobURL withSnapshot(String snapshot)
                           throws MalformedURLException,
                                  UnknownHostException

Creates a new AppendBlobURL with the given snapshot.

Overrides:

withSnapshot in class BlobURL

Parameters:

snapshot - A String of the snapshot identifier.

Returns:

An AppendBlobURL object with the given pipeline.

Throws:

MalformedURLException - Appending the specified snapshot produced an invalid URL.

UnknownHostException - If the url contains an improperly formatted ipaddress or unknown host address.

create

public io.reactivex.Single<AppendBlobCreateResponse> create(BlobHTTPHeaders headers,
                                                            Metadata metadata,
                                                            BlobAccessConditions accessConditions,
                                                            com.microsoft.rest.v2.Context context)

Creates a 0-length append blob. Call AppendBlock to append data to an append blob. For more information, see the Azure Docs.

Parameters:

headers - BlobHTTPHeaders

metadata - Metadata

accessConditions - BlobAccessConditions

context - Context offers a means of passing arbitrary data (key/value pairs) to an HttpPipeline's policy objects. Most applications do not need to pass arbitrary data to the pipeline and can pass Context.NONE or null. Each context object is immutable. The withContext with data method creates a new Context object that refers to its parent, forming a linked list.

Returns:

Emits the successful response.

appendBlock

public io.reactivex.Single<AppendBlobAppendBlockResponse> appendBlock(io.reactivex.Flowable<ByteBuffer> data,
                                                                      long length,

Commits a new block of data to the end of the existing append blob. For more information, see the Azure Docs. Note that the data passed must be replayable if retries are enabled (the default). In other words, the Flowable must produce the same data each time it is subscribed to.

Parameters:

data - The data to write to the blob. Note that this Flowable must be replayable if retries are enabled (the default). In other words, the Flowable must produce the same data each time it is subscribed to.

length - The exact length of the data. It is important that this value match precisely the length of the data emitted by the Flowable.

appendBlobAccessConditions - AppendBlobAccessConditions

context - Context offers a means of passing arbitrary data (key/value pairs) to an HttpPipeline's policy objects. Most applications do not need to pass arbitrary data to the pipeline and can pass Context.NONE or null. Each context object is immutable.
