Method Detail

checkFileName

Pair<String,Collection<byte[]>> checkFileName(String name,
                                              Collection<String> algorithms,
                                              long startOffset,
                                              long length,
                                              int blockSize)
                                       throws IOException

Parameters:

name - Remote file name/path

algorithms - Hash algorithms in preferred order

startOffset - Start offset of the hash

length - Length of data to hash - if zero then till EOF

blockSize - Input block size to calculate individual hashes - if zero the one hash of all the data

Returns:

A Pair where left=hash algorithm name, right=the calculated hashes.

Throws:

IOException - If failed to execute the command
