  - HCL Commerce database schema
    The HCL Commerce database model was designed for data integrity and optimal performance. HCL Commerce provides several hundred tables that store HCL Commerce instance data. To maintain data integrity, and to ease maintenance referential integrity, constraints are widely used in the database model. Indexes are used carefully on tables to avoid over-indexing and to provide a good balance between data retrieval and data manipulation activities (insert and update). The business rules are implemented at the application level rather than by using database trigger. Triggers, however, are used to facilitate data staging and optimistic locking. A limited number of SQL-based database stored procedures are used for data intensive activities.
  - Payments subsystem
    In HCL Commerce, payment processing uses the Payments subsystem.
  - Dynamic caching
    In general, caching improves response time and reduces system load. Caching techniques are used to improve the performance of World Wide Web Internet applications. Most techniques cache static content (content that rarely changes) such as graphic and text files. However, many websites serve dynamic content, containing personalized information or data that changes more frequently. Caching dynamic content requires more sophisticated caching techniques, such as those provided by the WebSphere Application Server dynamic cache, a built-in service for caching and serving dynamic content.
  - HCL Commerce store pages properties
  - Cache-entry elements
    The root element of the cachespec.xml file, <cache>, contains <cache-entry> elements. The WebSphere dynamic cache service parses the cachespec.xml file during start-up, and extracts a set of configuration parameters from each <cache-entry> element.
  - Data Load utility configuration file schema
    The Data Load utility contains several configuration files. You can use the configuration file schema to understand and customize the data load configuration files.
  - HCL Commerce web services
    HCL Commerce provides many web services.
  - Utilities
    In HCL Commerce utilities are scripts that perform operations such as loading access control policies, loading store data, and cleaning the database of obsolete objects. In runtime environments, run utilities from the Utility server Docker container. In the development environment, run utilities from the bin directory.
  - Shopping flow URLs

  - jQuery Enhancements API
    The Aurora starter store in HCL Commerce is completely written in jQuery, which is one of the most commonly used JavaScript libraries used in dynamic websites. The jQuery AJAX and events API provides an easy to use framework that meets most AJAX requirements for storefront development.
    - HCL Commerce AJAX framework
      The HCL Commerce AJAX framework is an extension of the jQuery AJAX framework. It provides an easy to use framework that meets most AJAX requirements for storefront development, and hides some of the complexity and repetitive code that a storefront developer often encounters.
    - AJAX framework
      The AJAX framework helps determine the refresh areas of pages, and the content that populates them. The framework helps track the status of store pages, and the content that is generated when customers interact with the store.
      - WCRefreshController.refresh(parameters)
        The WCRefreshController.refresh function refreshes the refresh area with the parameters specified. The parameters are passed as the data attribute into the JQuery.ajax call.
      - WCRefreshController.updateFormId(newFormId)
        The WCRefreshController.updateFormId function updates the form id that is passed to the AJAX call. If specified, all input elements in the specified form are passed as the data attribute into the JQuery.ajax call.
      - WCRefreshController.updateUrl(newURL)
        The WCRefreshController.updateUrl function allows developers to update the URL of the refresh area. The URL is usually defined in the JSP by using the refreshurl attribute, but in some circumstances you might need to change the URL.
      - wcRenderContext.declare
        The wcRenderContext.declare function declares a new refresh controller, associates it with the refreshAreaIds passed in and initializes it with the specified initialization properties. The initialization properties are in addition to the new refresh controller's properties. A refresh controller control refresh area widgets, and listens to changes in the render context and model and decides whether the registered refresh areas must be updated.
      - wcRenderContext.getRefreshAreaIds
        The wcRenderContext.getRefreshAreaIds function returns the refresh area IDs that are associated with the specified render context.
      - wcRenderContext.addRefereshAreaId
        The wcRenderContext.addRefereshAreaId function adds a refresh area ID to an existing render context.
      - wcRenderContext.getRenderContextProperties
        The wcRenderContext.getRenderContextProperties function returns the render context declared by the specified identifier.
      - wcRenderContext.updateRenderContext
        The wcRenderContext.updateRenderContext function retrieves the render context with the specified ID and applies the updates that are found in the specified updates object. After a context object is updated, the framework automatically calls all the renderContextChangedHandler methods of all the controllers.
      - wcRenderContext.testForChangedRC
        The wcRenderContext.testForChangedRC function searches the specified array of property names for a render context property that has changed since the last time a render context changed event was detected. It returns a value of true if any of the specified render context properties have changed, and returns a value of false if none of the specified render context properties have changed.
      - wcRenderContext.checkIdDefined
        The wcRenderContext.checkIdDefined function checks if a render context with the specified ID already exists. It returns true if there is an existing render context defined, false otherwise.
      - wcService.declare
        The wcService.declare function declares a new AJAX service with the specified ID. In HCL Commerce, a service is a server URL that performs a server object create, update, delete, or other server processing. When needed, a Transaction server URL is called by using AJAX in the JavaScript code. When the service completes successfully, a JSON object that contain all the response properties of the URL request is returned to successHandler (the success response) or failureHandler (the failure response) defined JavaScript function. In addition, a WCTopic.publish is sent to any subscribed listeners if the service completes successfully. In this case, the WCTopic.subscribe events listening to the specified topic will be triggered.
      - wcService.getServiceById
        The wcService.getServiceById helper function is for getting a handle on the service object that was declared by using the wcService.declare function. Once the service object is obtained, you can update any information in the service object such as URL, formId, or others. This function is helpful when you find a service and update its parameters before you invoke it.
      - wcService.invoke
        The wcService.invoke function finds the registered service with the specified service ID and invokes the service via AJAX by using the specified parameters.
    - User interface widgets
      The user interface widgets in the Aurora starter store extend the functionality of available jQuery widgets to create a versatile, customer-friendly store. They add new functionality, changing the appearance and interaction experience in the store.
  - HCL Commerce foundation tag library
    The HCL Commerce foundation JSTL tag library is a collection of custom tags that are provided to you to support the authoring of HCL Commerce JSP files. HCL Commerce stores use the JavaServer Pages Standard Tag Library (JSTL) to perform logic, instead of Java code. At the same time, business logic is moved into data beans. The combination of these steps allows for less Java code in a JSP page.

wcRenderContext.updateRenderContext (id, updates)

The wcRenderContext.updateRenderContext function retrieves the render context with the specified ID and applies the updates that are found in the specified updates object. After a context object is updated, the framework automatically calls all the renderContextChangedHandler methods of all the controllers.

Example

wcRenderContext.updateRenderContext('editShippingAddressContext', {
   'shippingAddress': '-1',
   'addressType': addressType
})

Parameters

id: (String) The render context ID.
updates: (Object) The render context updates. The properties of the object are added to the render context. Properties that have an undefined value are removed from the render context.
