All Implemented Interfaces:

Direct Known Subclasses:

Append, ParameterizedCopy

public class Copy
extends AbstractCommand

Copy a file to the given target directory or file. If the target is a directory the file name is preserved. If the target file exists it will be replaced if overwrite is true otherwise the command validation fails. If the source file is a directory, then the files it contents will be recursively copied.

If md5 is set then the copy command will be validated only if the target file has the same md5 as the one specified in the command.

The Copy command has as inverse either Delete either another Copy command. If the file was copied without overwriting then Delete is the inverse (with a md5 set to the one of the copied file). If the file was overwritten then the inverse of Copy command is another copy command with the md5 to the one of the copied file and the overwrite flag to true. The file to copy will be the backup of the overwritten file.
