Also 'atom' may be used as argument type by some internal commands, for example the ones that refer to erlang node names.

%% The 'any' and 'atom' argument types and 'any' result type
|
|
%% should only be used %% by commands with tag 'internal',
|
|
%% which are meant to be used only internally in ejabberd,
|
|
%% and not called using external frontends.
|
|
|
|
%% The purpose of a command can either be:
|
|
%% - informative: its purpose is to obtain information
|
|
%% - modifier: its purpose is to produce some change in the server
|
|
%%
|
|
%% A modifier command should be designed just to produce its desired side-effect,
|
|
%% and its result term should just be success or failure: rescode or restuple.
|
|
%%
|
|
%% ejabberd_web_admin:make_command/2 considers that commands
|
|
%% with result type different than rescode or restuple
|
|
%% are commands that can be safely executed automatically
|

%% to get information and build the web page.

|
|
%% - admin: Command is allowed for user that have Admin Rest command enabled by access rule: commands_admin_access

%% - user: Command might be called by any server user.
|
|
%% - open: Command can be called by anyone.
|
|
%%
|
|
%% Policy is just used to control who can call the command. A specific additional access rules can be performed, as
|
|
%% defined by access option.
|
|
%% Access option can be a list of:
|
|
%% - {Module, accessName, DefaultValue}: Reference and existing module access to limit who can use the command.
|
|
%% - AccessRule name: direct name of the access rule to check in config file.
|
|
%% TODO: Access option could be atom command (not a list). In the case, User performing the command, will be added as first parameter
|
|
%% to command, so that the command can perform additional check.
