Member Function Documentation

◆ execute()

ApiQueryDeletedrevs::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.

◆ getAllowedParams()

ApiQueryDeletedrevs::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

◆ getDescription()

ApiQueryDeletedrevs::getDescription ( )

Returns the description string for this module.

Returns
mixed string or array of strings

◆ getExamples()

ApiQueryDeletedrevs::getExamples ( )

Returns usage examples for this module.

Return false if no examples are available.

Returns
bool|string|array

◆ getParamDescription()

ApiQueryDeletedrevs::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.

◆ getPossibleErrors()

Returns
array

Reimplemented from ApiQueryBase.

Definition at line 524 of file ApiQueryDeletedrevs.php.

References array().

◆ getResultProperties()

ApiQueryDeletedrevs::getResultProperties ( )

Returns possible properties in the result, grouped by the value of the prop parameter that shows them.

Properties that are shown always are in a group with empty string as a key. Properties that can be shown by several values of prop are included multiple times. If some properties are part of a list and some are on the root object (see ApiQueryQueryPage), those on the root object are under the key PROP_ROOT. The array can also contain a boolean under the key PROP_LIST, indicating whether the result is a list.

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

Returns
array|bool False on no properties
