Method Detail

constructSignedChunk

protected byte[] constructSignedChunk(int userDataLen,
                                      byte[] userData)

Returns a chunk for upload consisting of the signed 'header' or chunk prefix plus the user data. The signature of the chunk incorporates the signature of the previous chunk (or, if the first chunk, the signature of the headers portion of the request).

Parameters:

userDataLen - The length of the user data contained in userData

userData - Contains the user data to be sent in the upload chunk

Returns:

A new buffer of data for upload containing the chunk header plus user data
