namespace Piwik\ViewDataTable;
use Piwik\Common;

/**
 * Contains base request properties for {@link Piwik\Plugin\ViewDataTable} instances. Manipulating
 * these properties will change the way a {@link Piwik\Plugin\ViewDataTable} loads report data.
 *
 * <a name="client-side-parameters-desc"></a>
 * **Client Side Parameters**
 *
 * Client side parameters are request properties that should be passed on to the browser so
 * client side JavaScript can use them. These properties will also be passed to the server with
 * every AJAX request made.
 *
 * Only affects ViewDataTables that output HTML.
 *
 * <a name="overridable-properties-desc"></a>
 * **Overridable Properties**
 *
 * Overridable properties are properties that can be set via the query string.
 * If a request has a query parameter that matches an overridable property, the property
 * will be set to the query parameter value.
 *
 * **Reusing base properties**
 *
 * Many of the properties in this class only have meaning for the {@link Piwik\Plugin\Visualization}
 * class, but can be set for other visualizations that extend {@link Piwik\Plugin\ViewDataTable}
 * directly.
 *
 * Visualizations that extend {@link Piwik\Plugin\ViewDataTable} directly and want to re-use these
 * properties must make sure the properties are used in the exact same way they are used in
 * {@link Piwik\Plugin\Visualization}.
 *
 * **Defining new request properties**
 *
 * If you are creating your own visualization and want to add new request properties for
 * it, extend this class and add your properties as fields.
 *
 * Properties are marked as client side parameters by calling the
 * {@link addPropertiesThatShouldBeAvailableClientSide()} method.
 *
 * Properties are marked as overridable by calling the
 * {@link addPropertiesThatCanBeOverwrittenByQueryParams()} method.
 *
 * ### Example
 *
 * **Defining new request properties**
 *
 *     class MyCustomVizRequestConfig extends RequestConfig
 *     {
 *         /**
 *          * My custom property. It is overridable.
 *          *\/
 *         public $my_custom_property = false;
 *
 *         /**
 *          * Another custom property. It is available client side.
 *          *\/
 *         public $another_custom_property = true;
 *
 *         public function __construct()
 *         {
 *             parent::__construct();
 *
 *             $this->addPropertiesThatShouldBeAvailableClientSide(array('another_custom_property'));
 *             $this->addPropertiesThatCanBeOverwrittenByQueryParams(array('my_custom_property'));
 *         }
 *     }
 *
 * @api
