Class PageBlobAsyncClient

java.lang.Object

com.azure.storage.blob.specialized.BlobAsyncClientBase

com.azure.storage.blob.specialized.PageBlobAsyncClient

public final class PageBlobAsyncClient
extends BlobAsyncClientBase

Client to a page blob. It may only be instantiated through a SpecializedBlobClientBuilder or via the method BlobAsyncClient.getPageBlobAsyncClient(). This class does not hold any state about a particular blob, but is instead a convenient way of sending appropriate requests to the resource on the service.

Please refer to the Azure Docs for more information.

Note this client is an async client that returns reactive responses from Spring Reactor Core project (https://projectreactor.io/). Calling the methods in this client will NOT start the actual network operation, until .subscribe() is called on the reactive response. You can simply convert one of these responses to a CompletableFuture object through Mono.toFuture().

Parameters:

source - The source page blob.

snapshot - The snapshot on the copy source.

modifiedAccessConditions - Standard HTTP Access conditions related to the modification of data. ETag and LastModifiedTime are used to construct conditions related to when the blob was changed relative to the given request. The request will fail if the specified condition is not satisfied.

Returns:

A reactive response emitting the copy status.

Throws:

IllegalStateException - If source and snapshot form a malformed URL.
