Manual:ApiBase.php/en

The  class implements many basic API functions, and is the base of all API classes. The class functions are divided into several areas of functionality:


 * Module parameters: Derived classes can define  to specify which parameters to expect, how to parse and validate them.
 * Profiling: various methods to allow keeping tabs on various tasks and their time costs
 * Self-documentation: code to allow the API to document its own state

getAllowedParams
Specify which parameters are allowed and what requirements are to be imposed on them. See the documentation beginning at line 46 for the constants PARAM_DFLT, PARAM_ISMULTI, PARAM_TYPE, PARAM_MAX, PARAM_MAX2, PARAM_MIN, PARAM_ALLOW_DUPLICATES, PARAM_DEPRECATED, PARAM_REQUIRED, and PARAM_RANGE_ENFORCE. The possible types of parameters are NULL, string, integer, limit, boolean, timestamp, user, or upload. A "user" parameter is a username that is validated using. For boolean parameters, a default value of anything other than 'false' is not allowed.

Example:

getResultProperties and getFinalResultProperties
