Constructor & Destructor Documentation

◆ __construct()

ApiFormatJson::__construct	(	ApiMain	$main,
			$format
	)

If $format ends with 'fm', pretty-print the output in HTML.

Parameters

ApiMain	$main
string	$format	Format name

Reimplemented from ApiFormatBase.

Member Function Documentation

◆ execute()

ApiFormatJson::execute ( )

Evaluates the parameters, performs the requested query, and sets up the result.

Concrete implementations of ApiBase must override this method to provide whatever functionality their module offers. Implementations must not produce any output on their own and are not expected to handle any errors.

The execute() method will be invoked directly by ApiMain immediately before the result of the module is output. Aside from the constructor, implementations should assume that no other methods will be called externally on the module before the result is processed.

The result data should be stored in the ApiResult object available through getResult().

Reimplemented from ApiBase.

Reimplemented in ApiOpenSearchFormatJson.

Definition at line 68 of file ApiFormatJson.php.

References $params, ApiBase\dieUsage(), ApiBase\extractRequestParams(), ApiFormatBase\getIsHtml(), ApiBase\getResult(), ApiFormatBase\printText(), and true.

◆ getAllowedParams()

ApiFormatJson::getAllowedParams ( )

Returns an array of allowed parameters (parameter name) => (default value) or (parameter name) => (array with PARAM_* constants as keys) Don't call this function directly: use getFinalParams() to allow hooks to modify parameters as needed.

Some derived classes may choose to handle an integer $flags parameter in the overriding methods. Callers of this method can pass zero or more OR-ed flags like GET_VALUES_FOR_HELP.

Returns: array

Reimplemented from ApiFormatBase.

Definition at line 122 of file ApiFormatJson.php.

References $ret, ApiBase\PARAM_DFLT, ApiBase\PARAM_HELP_MSG, and ApiBase\PARAM_TYPE.

◆ getMimeType()

ApiFormatJson::getMimeType ( )

Overriding class returns the MIME type that should be sent to the client.

When getIsHtml() returns true, the return value here is used for syntax highlighting but the client sees text/html.

Returns: string

Reimplemented from ApiFormatBase.

◆ getWantsHelp()

ApiFormatJson::getWantsHelp ( )
