 nsIControllerCommandTable
 
 An interface via which a controller can maintain a series of commands,
 and efficiently dispatch commands to their respective handlers.

 Controllers that use an nsIControllerCommandTable should support
 nsIInterfaceRequestor, and be able to return an interface to their
 controller command table via getInterface().

Methods

 Execute the named command.

 @param aCommandName    the name of the command to execute
 @param aCommandRefCon  the command context data
void doCommand(in string aCommandName, in nsISupports aCommandRefCon) 

        


  
  void
  doCommandParams(in string aCommandName, in nsICommandParams aParam, in nsISupports aCommandRefCon)


      

  

  
      

        
 Find the command handler which has been registered to handle the named command.

 @param aCommandName  the name of the command to find the handler for.


        


  
  nsIControllerCommand
  findCommandHandler(in string aCommandName)


      

  

  
      

        

        


  
  void
  getCommandState(in string aCommandName, in nsICommandParams aParam, in nsISupports aCommandRefCon)


      

  

  
      

        
 Get whether the named command is enabled.

 @param aCommandName    the name of the command to test
 @param aCommandRefCon  the command context data


        


  
  boolean
  isCommandEnabled(in string aCommandName, in nsISupports aCommandRefCon)


      

  

  
      

        
 Make this command table immutable, so that commands cannot
 be registered or unregistered. Some command tables are made
 mutable after command registration so that they can be 
 used as singletons.


        


  
  void
  makeImmutable()


      

  

  
      

        
 Register and unregister commands with the command table.

 @param aCommandName  the name of the command under which to register or
                      unregister the given command handler.

 @param aCommand      the handler for this command.


        


  
  void
  registerCommand(in string aCommandName, in nsIControllerCommand aCommand)


      

  

  
      

        
 Get whether the named command is supported.

 @param aCommandName    the name of the command to test
 @param aCommandRefCon  the command context data


        


  
  boolean
  supportsCommand(in string aCommandName, in nsISupports aCommandRefCon)


      

  

  
      

        

        


  
  void
  unregisterCommand(in string aCommandName, in nsIControllerCommand aCommand)


      

  

  
      

        
 Tell the command to udpate its state (if it is a state updating command)

 @param aCommandName    the name of the command to update
 @param aCommandRefCon  the command context data


        


  
  void
  updateCommandState(in string aCommandName, in nsISupports aCommandRefCon)
