MultipleCommandAlias example?

I want to have a plugin to do the equivalent of a Bukkit command alias, where one command executes two plugin commands, e.g.:

Code:

aliases:
  commandname:
  - essentials:commandname $$1
  - pluginname:commandname $$1

So in this example, the command commandname executes Essentials commandname and pluginname commandname, each requiring one parameter.

All I want to do is register the command alias. The commands would be executed when a player types /commandname in chat.

I'm thinking it can be done with the class MultipleCommmandAlias. Is that correct? Can anyone give me a brief example?

 

getServer().dispatchCommand(command)

 

I don't want to execute the command. I want to register an alias as if it was defined in commands.yml
