Modul:Classgenerator/class/doc

This is a Class Module. It implements a class in Lua using Module:Middleclass and the template class Module:Foundationclass. This class provides methods for PURPOSE.

Usage

local name = args[1] or args.name or mw.title.getCurrentTitle().rootText
local Class = require('Module:Name/class')
local me = Class:new(name)
me:initDataFromArgs(args)
me:storeData()
me:addInfobox()
me:addPageBody()
return me:render()

Methods

Constructor

new(uid)

Creates a new Object for the class.

uid

variable, optional

used to identify the object

return

object, of the class

public methods

addInfobox()

If no errors and data is present, adds an infobox to the object's output.

return

boolean, whether adding was successful or not

addPageBody()

Adds a page body (all content besides the infobox) to the object's output: Errors and Warnings, sample configuration, statistics, ... Of course, only if there is data.

return

boolean, whether adding was successful or not

myArgumentProcessing(coreData)

Performs the individual argument processing in initDataFromArgs(args) right before inititializing it.

coreData

table, mandatory

the core data of the object. the one to process individually before initialization

return

table, the new core data array to be used

myPlausibilityTest(args)

Performs the individual plausibility tests in initDataFromArgs(args) before entering the initialization part. NOTE: The return value will be ignored. If this finds errors, it must add them to the list of errors via addError(errortext).

args

table, mandatory

arguments passed to the template to be checked

return

boolean, whether the object is plausible or not.

myStashAdjustments(self, stash)

Performs the adjusts the stash in storeData() right before storing it.

stash

table, mandatory

the array of data to be saved (in the form fieldname: value)

return

boolean, the new stash

static methods

ClassClassgenerator:mySfDynamicFieldAttribute(fieldname, attribute, value)

For some semantic form fields there are attribute values, that are not static, thus can not be provided at forehand in the configuration file. This method does the trick to adapt them at runtime shortly before the field is rendered. Essentially: the method checks, if it has a special rule for the pair fieldname:attribute and if so, calculates the new value. if not, the old value is returned.

fieldname

string, mandatory

the form field's name, needed to match current paring to an existing special treatment rule

attribute

string, mandatory

the form field's attribute, needed to match current paring to an existing special treatment rule

value

variable, mandatory

the value, that is already provided in the configuration file. this will be adapted by the method, if there is a special rule for the pair fieldname:attribute.

return

string, the value to be used forthwith (which can be the old one or a freshly calculated)

private methods

_debug(self, level, text)

Adds output to the internal debug log.

self

object, me

level

int; mandatory

debug level for the message

text

string; mandatory

debug message text

return

void

_namespaceName (self, namespaceId)

Takes the id of a namespace and converts it to the human readable name. Normally returns mw.site.namespaces[id].canonicalName...

self

object, me

namespaceId

int; mandatory

for which namespace id the name should be returned

return

string, name of namespace

_processAttribute(self, attr, indent, name)

Takes an attribute and builds from that (and self:getCoreData()) one entry in the class's config file.

self

object, me

attr

string; mandatory

for which attribute should the entry be build

indent

string; mandatory

indentation of line

name

string; optional

normally the parameter name will be constructed out of attr. if you have special needs as a name, you can supply them via this parameter. name takes precedence, if provided.

return

string, the entry that can directly be added to the config file/string

Properties

static

See also Static Properties

ClassName.myConfiguration

this is your configuration. It is devided in several section, each a

table, holds configuration data found in Module:Name/config

WARNING: This is a read only table and besides functions pairs() and ipairs() nothing else will work on it, especially not the functions of the table library!

• form, table, holds data used to create the form. here are some of them:
  • formButtons, table, which buttons should be printed at the bottom
  • fieldOrder, table, in which order the form fields should appear (note: only fields listed here will be added to the form)
• global, table, holds some global configuration data
• parameter, table, holds all data about all parameter used in the module (be they form only, data store only or normal). The table has the form paramname = { table of paramdata }. The tables for the parameter have data as follows:
  • cardinality, string, mandatory, one of singe or list
  • cargo_type, string, optional, if the parameter is to be stored in cargo, add the field type here (one of Page, Text, Integer, Float, Date, Datetime, Boolean (which should be provided as 1 or 0), Coordinates, Wikitext, File, String, URL, or Email)
  • description, string, mandatory, a description of this parameter
  • label, string, mandatory, the label used in the form and the template documentation
  • severity, string, optional, if provided one of mandatory, suggested
  • sf, table, optional, used to add more attributes to the semantic forms field. ref Module:SFfield/config for all possible attributes. Note that the table is of type attribute_name : value. Value can be of type string, integer, boolean, and (in case of 'show on select') a table. Please note, that the attribute name cannot contain a " " (space). Use the underscore instead.
  • td_default, string, optional, if you want a default value to be indicated in the template data section on the documentation page, add it here
  • td_type, string, optional, if the parameter should be present in the template documentation page, fill this field. all possible values are listed here
  • values, table, optional, if you want the possible values to be restricted to a specific set, fill this table
• template, table, holds some data used only in the template

className.publicStaticProperty

type, explanation

_privateStaticProperty

type, explanation

private

Note: all private properties are stored in table _private[self]. _private is a static array that is indexed by self, so the table _private[self] holds all properties for instance self.

dbg

object, my instance of Module:Debug/class for debugging purposes. only present afer first call of _debug(self, level, text)

Configuration Data

This class holds its control data in Module:Classgenerator/class/config.

Inheritance

Methods

Note: You still reference those either by self:publicMethod() or Classgenerator:staticMethod() and Classgenerator.staticProperty respectively!

Constructor

new(uid, superhandler)

Creates a new Object for the class.

uid

variable, suggested

used to identify the object. defaults to mw.title.getCurrentTitle().prefixedText

data

table, mandatory

a data table coming directly from the data store

return

table, the new data table suiteable for argument processing

myPlausibilityTest(args)

args

table, mandatory

arguments passed to the template to be checked

return

boolean, whether the object is plausible or not.

myStashAdjustments(stash, storeType)

return

table, the new stash

FoundationClass:mySfDynamicFieldAttribute(fieldname, attribute, value)

For some semantic form fields there are attribute values, that are not static, thus can not be provided at forehand in the configuration file. This method does the trick to adapt them at runtime shortly before the field is rendered. Essentially: the method checks, if it has a special rule for the pair fieldname:attribute and if so, calculates the new value. if not, the old value is returned. Note, that you can completely disable a form field with this when you return false on attribute "disable".

fieldname

string, mandatory

attribute

string, mandatory

the form field's attribute, needed to match current paring to an existing special treatment rule

value

variable, mandatory

the value, that is already provided in the configuration file. this will be adapted by the method, if there is a special rule for the pair fieldname:attribute.

return

string, the value to be used forthwith (which can be the old one or a freshly calculated)

Public methods

 

addCategory(category)

Prepares to add the page to category category. Note: until you actually call render() or renderCategories(), this will not be implemented

return

boolean, whether adding was successful or not

addInfobox()

If no errors and data is present, adds an infobox to the object's output. NOTE: This is a shell method and should be overwritten!

return

boolean, whether adding was successful or not

addOutput(content)

Adds something to the page's output. Something can be of type string, int, or table (that needs to have __tostring() implemented)

content

string, int, or table; mandatory

content element that is added to page's output

return

boolean, whether adding was successful or not

addPageBody()

Adds a page body (all content besides the infobox) to the object's output: Errors and Warnings, sample configuration, statistics, ... Of course, only if there is data. NOTE: This is a shell method and should be overwritten!

getCoreData()

Returns the table of coreData

return

table, the value for _private[self].coreData, emtpy if not initialized

goodToGo()

Is this a proper object (with data and no errors)

return

boolean, whether we are proper initialized

initFromArgs(args)

Initializes the object with a data table, containing arguments (template parameter). Does plausibility tests and mangling of input and either fills list of errors or adds input to the object's data. {{{1}}}

initFromData(data)

Initializes the object with a data table, coming from the datastore. Depending on datastore, that means that the table keys might be different than when using arguments form the template. Does plausibility tests and mangling of input and either fills list of errors or adds input to the object's data. {{{1}}}

initMyself(uid)

Initializes the object with data from the data store. The method queries for the object's uid in the container defined by Foundationclass.globalConfig.uidFieldName (can be set to an infividual name in Module:Foundationclass/globalconfig) in either the class's table (in case of datastore cargo) or for objects that have Foundationclass.globalConfig.smwClassProperty set to class.name (in case of datastore smw). The uid was either passed to the method (priority) or submitted to the constructor. Does NOT do plausibility tests and mangling of input but assumes the data comes directly from the data store and thus can be trusted (i.e. passes _plausibilityTest())

uid

string, optional

the data, the object can use to identify itself. This field can be omitted, in which case the uid that was submitted to the constructor will be used.

return

boolean, whether initialization was successful or not

render()

Renders the object's output

return

string, the textual representation of the object (which can vary, depending on what add*-methods you called before)

renderCategories()

Renders the object's categories (if any), thus adding them to the output stream and in turn sorting the page in it, if and only if render() is called on the object's page (when self:getUid == Classgenerator/class/doc).

return

object of type mw.html, the wikitext necessary to add the page to the categories

renderErrors()

Renders the object's errors (if any)

return

object of type mw.html, the representation of the list of errors

renderWarnings()

Renders the object's warnings (if any)

return

object of type mw.html, the representation of the list of warnings

setSortkey(sortkey)

Sets a default sortkey for this page using the magic word DEFAULTSORT. Only applies, if no superhandler is given.

sortkey

string, mandatory

new sortkey for this page

return

void

setUid(value)

Sets my uid to the given value. normally this should be set by constructor

value

string/integer, mandatory

new valued for my uid

return

boolean, true/false

storeData()

If this was initialized with outside data and there are no errors, stores the arguments in an appropriate data store (smw or cargo). In case of cargo, also calls the necessary #cargo_declare parser function if in the template namespace.

return

boolean, whether store was successful or not

return

string, the input field, that lints to the form

FoundationClass:sfGenerateFormTable(fieldlist)

Generates a table that can be used in a form inside the {{{for template}}} tag.
