    • Method Detail

      • getBlobOutputStream

        public BlobOutputStream getBlobOutputStream()
        Creates and opens an output stream to write data to the block blob.

        Note: We recommend you call write with reasonably sized buffers, you can do so by wrapping the BlobOutputStream obtained below with a BufferedOutputStream.

        Returns:
        A BlobOutputStream object used to write data to the blob.
        Throws:
        BlobStorageException - If a storage service error occurred.

      • getBlobOutputStream

        public BlobOutputStream getBlobOutputStream​(boolean overwrite)
        Creates and opens an output stream to write data to the block blob.

        Note: We recommend you call write with reasonably sized buffers, you can do so by wrapping the BlobOutputStream obtained below with a BufferedOutputStream.

        Parameters:
        overwrite - Whether to overwrite, should data exist on the blob.
        Returns:
        A BlobOutputStream object used to write data to the blob.
        Throws:
        BlobStorageException - If a storage service error occurred.

      • upload

        public BlockBlobItem upload​(InputStream data,
                            long length)
        Creates a new block blob. By default, this method will not overwrite an existing blob. Updating an existing block blob overwrites any existing metadata on the blob. Partial updates are not supported with PutBlob; the content of the existing blob is overwritten with the new content. To perform a partial update of a block blob's, use PutBlock and PutBlockList. For more information, see the Azure Docs.

        Code Samples

         System.out.printf("Uploaded BlockBlob MD5 is %s%n",
     Base64.getEncoder().encodeToString(client.upload(data, length).getContentMd5()));
        Parameters:
        data - The data to write to the blob. The data must be markable. This is in order to support retries. If the data is not markable, consider using getBlobOutputStream() and writing to the returned OutputStream. Alternatively, consider wrapping your data source in a BufferedInputStream to add mark support.
        length - The exact length of the data. It is important that this value match precisely the length of the data provided in the InputStream.
        Returns:
        The information of the uploaded block blob.
        Throws:
        UncheckedIOException - If an I/O error occurs

        sourceContentMd5 - An MD5 hash of the block content. This hash is used to verify the integrity of the block during transport. When this header is specified, the storage service compares the hash of the content that has arrived with this header value. Note that this MD5 hash is not stored with the blob. If the two hashes do not match, the operation will fail.
        leaseId - The lease ID that the active lease on the blob must match.
        sourceRequestConditions - BlobRequestConditions
        timeout - An optional timeout value beyond which a RuntimeException will be raised.
        context - Additional context that is passed through the Http pipeline during the service call.
        Returns:
        A response containing status code and HTTP headers
        Throws:
        IllegalArgumentException - If sourceUrl is a malformed URL.
