Callback Methods Common to All Modules
This page covers all callbacks that all module types may or
are expected to implement in order to function as a proper roxen
module. (Be sure to see the sections on common constants and API methods too.) |
|
- void create(Configuration|void conf)
-
In create(), you typically define your module's
configurable variables (using the
defvar() method) and set data
about it using set_module_creator() and
set_module_url(). The
configuration object
of the virtual server the module was initialized in is always passed,
except for the one occasion when the file is compiled for the first
time, when the `conf' argument passed is 0. Se also
start().
- string info(Configuration|void conf)
-
Implementing this function in your module is optional.
When present, it returns a string that describes the module. When
absent, Roxen will use element module_doc. Unlike
module_doc, though, this information is only shown when the module is
present in a virtual server, so it won't show up when adding modules
to a server.
- void start(int occasion, Configuration conf)
-
Set up shop / perform some action when saving variables. (optional)
If occasion is 0, we're being called when starting up the module,
to perform whatever actions necessary before we are able to service
requests. This call is received when the virtual server the module
belongs to gets initialized, just after the module is successfully
added by the administrator or when reloading the module.
This method is also called with occasion set to 2 whenever the
configuration is saved, as in when some module variable has changed
and the administrator clicked "save" in the admin interface. This
also happens just before calling stop() upon reloading
the module.
- void stop()
-
Close down shop. (optional)
Tidy up before the module is terminated. This method is called
when the administrator drops the module, reloads the module or
when the server is being shut down.
- string status()
-
Tells some run-time status, statistics or similar to the curious
administrator. Implementing this function is optional.
Returns a string of HTML that will be put in the admin interface on
the module's settings page just below the
documentation string.
- mapping|int(-1..0)|Stdio.File find_internal(string file, RequestID id)
-
Internal magic location any module may use, similar to the
find_file() method of all Location (Filesystem) Modules, but with a less civilized-looking URL
(typically prefixed with the string "/internal/" prepended to
your module identifier). This method is mostly used for background
things where a URL doesn't show too much, such as when generating
background images and the like. To get the internal mountpoint below
which find_internal will handle requests, use
query_internal_location().
