Method Detail

execute

public Continuation execute(AppCommandParser parser,
                            Session session,
                            Output out)

Description copied from interface: App

The actual code for the application.

Specified by:

execute in interface App

Overrides:

execute in class TransactionProvidingApp

Parameters:

parser - holds the options (w/ or w/o values) as well as arguments.

session - the client session (sort of like the environment for the execution).

out - the output channel for the execution, just like System.out.

Returns:

the result of the execution. It is up to the client to interpret this string, one example is that all apps returns null and the "exit" app returns "e" so that the server interprets the "e" as a sign that it should exit.

Throws:

Exception - if the execution fails.
