Module:SSC base/doc

This is a base class to be inherited by special entity classes. It provides basic functionality like argument plausibility tests, semantic storage, display of an infobox, etc.

Access to the semantíc data (reading and writing) is provided by Extension:Semantic Scribunto.

Usage

To build an entity class, create an appropriate config module. Use Module:SSC base/config as a template. Then put the following code on a module page to build the entity class:

local config = mw.loadData( 'Module:<entity module>/config' )
local baseClass = require( 'Module:SSC base' )

local class = baseClass:new( config )

return class

Suggested structure

Module:Entity

Holds all the functions, that can be invoked on a template or a normal page

Module:Entity/class

Here you inherit from Module:SSC base and extend your entity class

Module:Entity/config

Holds the configuration for your entity. A template can be found on Module:SSC base/config.

"Abstract" methods

There are several methods in this class that should/can be implemented by your entity class.

setDefaults( data )

Can be used to insert some defaults into the datastream after arguments from the template call are processed but before they are stored semantically. Here is the husk:

function class:setDefaults( data )
	local data = data
	-- for example
	data.title = data.title or mw.title.getCurrentTitle().text
	return data
end

data is a table that holds your arguments after preprocessing. Insert your defaults but don't forget to return the data table at the end.

alterDataAfterStorage( data )

Manipulates the data table after semantic data is stored but before the infobox is displayed.

function class:alterDataAfterStorage( data )
	local data = data
	-- for example
	data.header1 = 'Base data'
	return data
end

Note: a field in your data table is only added to your infobox, if the class' configuration says so.

Public methods

renderPage()

This is usually called in a function, which is invoked on the entity's module page. It provides this functions:

1. filter known and existant argument data from template arguments
2. checks for existance of mandatory arguments
3. converts all list fields into a table
4. saves the semantic data
5. builds a nice infobox (utilizing Module:Infobox)
6. places the page in the appropriate category

local entity = require( 'Module:<entity module>/class' ):new()
return entity:renderPage()
