Interface ICmd

All Known Subinterfaces:
ICmd.IActionDependent, ICmd.IConfirm, ICmd.IDisj, ICmd.IPwd, ICmd.ITog

public interface ICmd

to be implemented by any user-interface (interactive) commands your app might incorporate. These may not then be invoked directly, but should be passed to the static methods of Exes, in order to create executable Exes.

The available subinterfaces may be impl'ted in any combination, their respective methods being processed in the following order:

  1. ICmd.ITog
  2. ICmd.IActionDependent
  3. ICmd.IDisj
  4. ICmd.IConfirm
  5. ICmd.IPwd

Method Detail


String execute()
               throws Exception
called when the command is executed.

message indicating (to the user) that the command succeeded. If non-null, this is passed to ICmdsApp.postSucceeded(String) if an impl'n was supplied.
Exception - This will be caught and passed to the ICmdsApp.postFailed(Exception) impl'n (if supplied). Note that your implementation should only declare those Exceptions which the compiler obliges it to declare.
