ScpCommand

public ScpCommand(String command,
                  org.apache.sshd.common.util.threads.CloseableExecutorService executorService,
                  int sendSize,
                  int receiveSize,
                  ScpFileOpener fileOpener,
                  ScpTransferEventListener eventListener)

Parameters:

command - The command to be executed

executorService - An CloseableExecutorService to be used when start(Environment)-ing execution. If null an ad-hoc single-threaded service is created and used.

sendSize - Size (in bytes) of buffer to use when sending files

receiveSize - Size (in bytes) of buffer to use when receiving files

fileOpener - The ScpFileOpener - if null then DefaultScpFileOpener is used

eventListener - An ScpTransferEventListener - may be null
