                             long length,
                             AccessCondition accessCondition,

            throws StorageException,
                   IOException

Uploads the source stream data to the append blob using the specified lease ID, request options, and operation context. If the blob already exists on the service, it will be overwritten.

If you want to append data to an already existing blob, please see appendBlock(InputStream, long).

If you are doing writes in a single writer scenario, please look at BlobRequestOptions.setAbsorbConditionalErrorsOnRetry(Boolean) and see if setting this flag to true is acceptable for you.

Specified by:

upload in class CloudBlob

Parameters:

sourceStream - An InputStream object to read from.

length - A long which represents the length, in bytes, of the stream data, or -1 if unknown.

accessCondition - An AccessCondition object which represents the access conditions for the blob.

options - A BlobRequestOptions object that specifies any additional options for the request. Specifying null will use the default request options from the associated service client ( CloudBlobClient).

opContext - An OperationContext object which represents the context for the current operation. This object is used to track requests to the storage service, and to provide additional runtime information about the operation.

Throws:

IOException - If an I/O exception occurred.

StorageException - If a storage service error occurred.

setStreamWriteSizeInBytes

public void setStreamWriteSizeInBytes(int streamWriteSizeInBytes)

Sets the number of bytes to buffer when writing to a BlobOutputStream.

Specified by:

setStreamWriteSizeInBytes in class CloudBlob

Parameters:

streamWriteSizeInBytes - An int which represents the maximum block size, in bytes, for writing to an append blob while using a BlobOutputStream object, ranging from 16 KB to 4 MB, inclusive.

Throws:

IllegalArgumentException - If streamWriteSizeInBytes is less than 16 KB or greater than 4 MB.
