Public Member Functions

 getBodyParamSettings ()
 Fetch ParamValidator settings for body fields.Parameters defined by this method are used to validate the request body. The parameter values will become available through getValidatedBody().Subclasses may override this method to specify what fields they support in the request body. All parameter settings returned by this method must have self::PARAM_SOURCE set to 'body'.
Returns
array[]

 
 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.

Protected Member Functions

 generateResponseSpec (string $method)
 Returns an OpenAPI Responses Object specification structure as an associative array.
 
 getActionModuleParameters ()
 Maps a REST API request to an action API request.Implementations typically use information returned by $this->getValidatedBody() and $this->getValidatedParams() to construct the return value.The return value of this method controls which action module is called by execute().
Returns
array Emulated request parameters to be passed to the ApiModule.

 
 getTitleParameter ()
 Returns the requested title.
Returns
string

 
 mapActionModuleResult (array $data)
 Maps an action API result to a REST API result.

 throwHttpExceptionForActionModuleError (IApiMessage $msg, $statusCode=400)
 Throws a HttpException for a given IApiMessage that represents an error.Never returns normally.Subclasses may override this to provide mappings for specific error codes, typically based on $msg->getApiCode(). Subclasses overriding this method must always either throw an exception, or call this method in the parent class, which then throws an exception.
Stability: stable

Parameters
IApiMessage$msgA message object representing an error in an action module, typically from calling getStatusValue()->getMessages( 'error' ) on an ApiUsageException.
int$statusCodeThe HTTP status indicated by the original exception
