Interface Command

All Known Implementing Classes:

AbstractCommand, DELCommand, GETCommand, PUTCommand

public interface Command

Interface for a command in the Transport plugin. A Command is designed to handle a certain function like uploading a file. A Command is split into States that handle the next phase of a command. States are chained in the correct order by the Command. The methods setNextState(State) and handleState() are used for that.
