Detailed Description

API JSON output formatter.

Definition at line 31 of file ApiFormatJson.php.

Constructor & Destructor Documentation

◆ __construct()

ApiFormatJson::__construct (   $main,
  $format 
)

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

Parameters
$mainApiMain
string$formatFormat name

Reimplemented from ApiFormatBase.

Definition at line 35 of file ApiFormatJson.php.

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.

References $params, FormatJson\ALL_OK, FormatJson\encode(), ApiBase\extractRequestParams(), ApiFormatBase\getIsHtml(), ApiBase\getResultData(), ApiFormatBase\printText(), and FormatJson\XMLMETA_OK.

◆ 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|bool

Reimplemented from ApiBase.

Definition at line 87 of file ApiFormatJson.php.

References array().

◆ getDescription()

ApiFormatJson::getDescription ( )

Returns the description string for this module.

Returns
mixed string or array of strings

Reimplemented from ApiFormatBase.

Reimplemented in ApiFormatYaml.

Definition at line 103 of file ApiFormatJson.php.

◆ getMimeType()

ApiFormatJson::getMimeType ( )

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

This method is not called if getIsHtml() returns true.

Returns
string

Reimplemented from ApiFormatBase.

Reimplemented in ApiFormatYaml.

Definition at line 40 of file ApiFormatJson.php.

References $params, and ApiBase\extractRequestParams().

◆ getNeedsRawData()

ApiFormatJson::getNeedsRawData ( )

Whether this formatter needs raw data such as _element tags.

Returns
bool

Reimplemented from ApiFormatBase.

Definition at line 50 of file ApiFormatJson.php.

References $mIsRaw.

◆ getParamDescription()

ApiFormatJson::getParamDescription ( )

Returns an array of parameter descriptions.

Don't call this function directly: use getFinalParamDescription() to allow hooks to modify descriptions as needed.

Returns
array|bool False on no parameter descriptions

Reimplemented from ApiBase.

Definition at line 94 of file ApiFormatJson.php.

References array().

◆ getWantsHelp()

ApiFormatJson::getWantsHelp ( )

Whether this formatter can format the help message in a nice way.

By default, this returns the same as getIsHtml(). When action=help is set explicitly, the help will always be shown

Returns
bool

Reimplemented from ApiFormatBase.
