checkFileHandle
public java.util.AbstractMap.SimpleImmutableEntry<java.lang.String,java.util.Collection<byte[]>> checkFileHandle(SftpClient.Handle handle, java.util.Collection<java.lang.String> algorithms, long startOffset, long length, int blockSize) throws java.io.IOException
- Specified by:
checkFileHandle
in interfaceCheckFileHandleExtension
- Parameters:
handle
- Remote fileSftpClient.Handle
- must be a file and opened for readalgorithms
- Hash algorithms in preferred orderstartOffset
- Start offset of the hashlength
- Length of data to hash - if zero then till EOFblockSize
- Input block size to calculate individual hashes - if zero the one hash of all the data- Returns:
- An immutable
Map.Entry
where key=hash algorithm name, value=the calculated hashes. - Throws:
java.io.IOException
- If failed to execute the command
