updateViewCache

public void updateViewCache(PersistenceManager manager,
                            java.lang.String sourcePath,
                            java.lang.String scopeId,
                            java.lang.String newcacheFolder)
                     throws javax.naming.NamingException

Updates (or creates) view cache in BI Beans Catalog

Parameters:

manager - Instance of Persistence Manager

sourcePath - Source view path within BI Beans Catalog (relative to the Persistence Manager context)

scopeId - Scope ID for the cached object. Scope ID is used to distinguish cached objects created for different users or groups of users

newcacheFolder - Folder where cached objects will be saved upon creation (objects that are updated will not be affected by this parameter).

updateViewCache

public static void updateViewCache(PersistenceManager manager,
                                   java.lang.String sourcePath,
DataviewCommon sourceView,
                                   java.lang.String scopeId,
                                   java.lang.String newcacheFolder)
                            throws javax.naming.NamingException

Updates (or creates) view cache in BI Beans Catalog

Parameters:

manager - Instance of Persistence Manager

sourcePath - Source view path within BI Beans Catalog (relative to the Persistence Manager context)

sourceView - View to be cached

scopeId - Scope ID for the cached object. Scope ID is used to distinguish cached objects created for different users or groups of users

newcacheFolder - Folder where cached objects will be saved upon creation (objects that are updated will not be affected by this parameter).

getCachedView

public static DataviewCommon getCachedView(PersistenceManager manager,
                                           java.util.Hashtable appEnv,
                                           java.lang.String sourcePath,
                                           java.lang.String scopeId)
                                    throws javax.naming.NamingException

Retrieves a cached view from BI Beans Catalog

Parameters:

manager - Instance of Persistence Manager

appEnv - Environment to be passed to persistence manager's lookup() method. This parameter is useful if you want to pass extra information to your custom Peristence Object Factory.

sourcePath - Path to the original source view (not the cached view) within BI Beans Catalog

scopeId - Scope ID for the cached object. Scope ID is used to distinguish cached objects created for different users or groups of users

Returns:

view instance (exact instance type, including "thick" vs. "thin" will be determined by the Persistence manager's Object Factory).

deleteViewCache

public static boolean deleteViewCache(PersistenceManager manager,
                                      java.lang.String viewPath,
                                      java.lang.String scopeId)
                               throws javax.naming.NamingException

Deletes view cache from the BI Beans Catalog

Parameters:

manager - Instance of Persistence Manager

viewPath - path within BI Beans Catalog (relative to the Persistence Manager context) for the view whcih cache should be deleted

scopeId - Scope ID for the cached object. Scope ID is used to distinguish cached objects created for different users or groups of users

Returns:

a boolean value indicating whether cache was successfully deleted
