DESCRIPTION

This module handles the core functionality of the dispatch table system. This includes the dispatch table itself and the run() method that dispatches requested commands. In addition, this module handles aliasing functionality.

INTERFACE

new( $command_hash, $alias_hash )

Create a new App::CmdDispatch::Table object. This method can take one or two hashrefs as arguments. The first is required and describes the commands. The second is optional and provides a mapping of aliases to the command string that the alias maps to.

run( $cmd, @args )

Given a command string (or possibly an alias) and a set of arguments, this method executes the associated code.

command_list()

This method return the list of commands in sorted order. This is basically the keys of the dispatch table.

get_command( $cmd )

This method returns the hash that represents the supplied command.

alias_list()

This method returns a sorted list of the aliases in this table.

get_alias( $alias )

This method returns the string that the supplied alias maps to.
