Member Function Documentation

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.

Here is the call graph for this function:

ApiQueryRandom::executeGenerator ( resultPageSet)

Execute this module as a generator.

Parameters:
$resultPageSetApiPageSet: All output should be appended to this object

Reimplemented from ApiQueryGeneratorBase.

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.

Returns:
array or false

Get the cache mode for the data generated by this module.

Override this in the module subclass. For possible return values and other details about cache modes, see ApiMain::setCacheMode()

Public caching will only be allowed if *all* the modules that supply data for a given request return a cache mode of public.

Parameters:
$params
Returns:
string

Reimplemented from ApiQueryBase.

Definition at line 135 of file ApiQueryRandom.php.

Returns the description string for this module.

Returns:
mixed string or array of strings

Reimplemented from ApiBase.

Definition at line 164 of file ApiQueryRandom.php.

Returns usage examples for this module.

Return false if no examples are available.

Returns:
false|string|array

Reimplemented from ApiBase.

Definition at line 173 of file ApiQueryRandom.php.

Returns an array of parameter descriptions.

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

Returns:
array or false

Reimplemented from ApiBase.

Definition at line 156 of file ApiQueryRandom.php.

Returns a string that identifies the version of the extending class.

Typically includes the class name, the svn revision, timestamp, and last author. Usually done with SVN's Id keyword

Returns:
string
