Inspecting commands

It is possible to inspect a dispatcher and get the commands that have been registered on it.

Listing

To get a list of commands, getCommands() will return a set of CommandMapping instances, which provide complete information about all registered commands.

Set<CommandMapping> mappings = dispatcher.getCommands();
for (CommandMapping mapping : mappings) {
    String commandName = mapping.getPrimaryAlias();
    String[] allAliases = mapping.getAllAliases();
    CommandCallable callable = mapping.getCallable();
    Description desc = mapping.getDescription();
    String descText = desc.getShortDescription();
}

This can be used to create a help feature.

Specific commands

Use get(String alias) to get a command by any of it aliases.

In addition, contains(String alias) will check if a dispatcher contains a command.
