Public Member Functions

 checkPreconditions ()
 Check the conditional request headers and generate a response if appropriate.
 
 execute ()
 Transform content given in the request from or to wikitext.
 
 getParamSettings ()
 Fetch ParamValidator settings for parameters.Every setting must include self::PARAM_SOURCE to specify which part of the request is to contain the parameter.Can be used for the request body as well, by setting self::PARAM_SOURCE to "post". Note that the values of "post" parameters will be accessible through getValidatedParams(). "post" parameters are used with form data (application/x-www-form-urlencoded or multipart/form-data).For "query" parameters, a PARAM_REQUIRED setting of "false" means the caller does not have to supply the parameter. For "path" parameters, the path matcher will always require the caller to supply all path parameters for a route, regardless of the PARAM_REQUIRED setting. However, "path" parameters may be specified in getParamSettings() as non-required to indicate that the handler services multiple routes, some of which may not supply the parameter.
Stability: stable
to override
Returns
array[] Associative array mapping parameter names to ParamValidator settings arrays

 
 needsWriteAccess ()
 Indicates whether this route requires write access to the wiki.Handlers may override this method to return false if and only if the operation they implement is "safe" per RFC 7231 section 4.2.1. A handler's operation is "safe" if it is essentially read-only, i.e. the client does not request nor expect any state change that would be observable in the responses to future requests.Implementations of this method must always return the same value, regardless of the parameters passed to the constructor or system state.Handlers for GET, HEAD, OPTIONS, and TRACE requests should each implement a "safe" operation. Handlers of PUT and DELETE requests should each implement a non-"safe" operation. Note that handlers of POST requests can implement a "safe" operation, particularly in the case where large input parameters are required.The information provided by this method is used to perform basic authorization checks and to determine whether cross-origin requests are safe.
