Method Details

checkFileName

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

Specified by:

checkFileName in interface CheckFileNameExtension

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:

An immutable Map.Entry key left=hash algorithm name, value=the calculated hashes.

Throws:

IOException - If failed to execute the command
