Overrides base class to prepend 'g' to every generator parameter.

Parameters
string$paramNameParameter name
Returns
string Prefixed parameter name

Reimplemented from ApiBase.

Definition at line 662 of file ApiQueryBase.php.

◆ executeGenerator()

◆ getPageSet()

ApiQueryGeneratorBase::getPageSet ( )
protected

Get the PageSet object to work on.

If this module is generator, the pageSet object is different from other module's

Returns
ApiPageSet

Reimplemented from ApiQueryBase.

protected

◆ setGeneratorMode()

ApiQueryGeneratorBase::setGeneratorMode ( ApiPageSet  $generatorPageSet)

Switch this module to generator mode.

By default, generator mode is switched off and the module acts like a normal query module.

Since
1.21 requires pageset parameter
Parameters
