The atg.projects.store.assembler.cartridge.PriceSliderContentItem class represents the content item that the PriceSlider cartridge returns to the renderer. The PriceSliderContentItem class has these properties:
filterCrumb: This property references thecom.endeca.infront.cartridge.model.RangeFilterBreadcrumbobject that is created by thePriceSliderHandlerwhenever price slider settings have been applied for the current query. Continue reading below for more information on this object and how it is used.priceProperty: This property references the record property that the slider is based on which, in this case, issku.activePrice.sliderMin: Specifies the lower end point for the price slider.sliderMax: Specifies the upper end point for the price slider.enabled: Indicates whether the price slider should be rendered. When this property is set totrue, the slider is rendered. When it is set tofalse, it is not rendered. ThePriceSliderHandlersets this property based on the number of results returned for the query. If 0 or 1 result is returned,PriceSliderHandlersets this property to false.
The /atg/endeca/assembler/cartridge/handler/PriceSlider component, which is of class atg.projects.store.assembler.cartridge.handler.PriceSliderHandler, is responsible for creating and populating the PriceSliderContentItem object. The PriceSliderHandler class is an extension of the com.endeca.infront.cartridge.NavigationCartridgeHandler class and it overwrites the preprocess() and process() methods.
The PriceSliderHandler.preprocess() method creates an MDEX request but does not execute it. The process() method executes the MDEX request to get the search results. It also retrieves the current com.endeca.infront.navigation.NavigationState object using the /atg/endeca/assembler/cartridge/manager/NavigationState component referenced by the PriceSliderHandler component’s navigationStateProperty. The NavigationState object contains the navigation choices that have led to the current result set, including any range filters that have been applied and the properties those range filters have been applied to. If an existing range filter has been applied to the sku.activePrice property, it is an indicator that the price slider has already been applied to the current result set and the rendering of the price slider must take into account the existing settings. To do this, the PriceSliderHandler creates a com.endeca.infront.cartridge.model.RangeFilterBreadcrumb object and populates it with data from the range filter. Specifically, the RangeFilterBreadcrumb includes:
The name of the property the range filter was applied to, the
sku.activePriceproperty.The operation name, in this case,
BTWNfor the between operation.The upper and lower bounds of the range filter.
The PriceSliderHandler then sets the PriceSliderContentItem.filterCrumb property to reference this RangeFilterBreadcrumb object, thereby making the existing slider settings available to the JSP renderer.
The PriceSliderHandler also sets the slider end points by retrieving the priceSliderMaximumValue and priceSliderMinimumValue properties for the currently searched site (or sites) from the Site repository. The priceSliderMaximumValue and priceSliderMinimumValue properties are site-specific and can be configured through the Site Administration UI. If the current results come from more than one site, the PriceSliderHandler uses the lowest priceSliderMinimumValue and the highest priceSliderMaximumValue from the sites. If no values have been set, PriceSliderHandler uses the defaults of 0 and 1500 for the minimum and maximum values, respectively.
Finally, the PriceSliderHandler evaluates the number of results returned for the query and sets the PriceSliderContentItem.enabled property to true if there is more than one result and false if there is 0 or 1 result.
The PriceSlider component has the following configurable properties:
storeSitePropertiesManager: Specifies the component thatPriceSliderHandleruses to retrieve the names of the site properties that store the slider minimum and slider maximum values.PriceSliderHandlerthen queries the sites, uses these names, to get the values. Out of the box, this property is set to/atg/multisite/StoreSitePropertiesManager.searchedSites: Specifies the component thatPriceSliderHandleruses to determine which sites have contributed records to the current results set.siteManager: Specifies the component thatPriceSliderHandleruses to retrieve sites from the Site repository.
The PriceSlider component also inherits a number of properties from the /atg/endeca/assembler/cartridge/handler/NavigationCartridgeHandler component, through a $basedOn property configuration. Specifically, PriceSlider inherits a reference to the /atg/endeca/assembler/cartridge/manager/NavigationState component that provides information on the shopper’s current navigation state.
