      • cutStringToByteLength

        public static java.lang.String cutStringToByteLength​(java.lang.String str,
                                                     int max)
        truncates a string to a certain byte length. is assumes that each non-ascii character takes 2 bytes space which is considered for how much has to be cut off.
        Parameters:
        max - the allowed max byte length

      • preloadLocalizedProperties

        public static void preloadLocalizedProperties​(java.util.Set<PK> langPKs,
                                              java.util.Collection<LocalizableItemRemote> _items)

      • getProperties

        public static EJBPropertyRowCache getProperties​(TypeInfoMap infoMap,
                                                PK itemPK,
                                                PK typePK,
                                                PK langPK,
                                                long timestamp)
        reads all unlocalized or localized properties of one language for a specified item in a property cache object.
        Parameters:
        itemPK - the PK of the item these properties belong to
        typePK - the item type - this is needed to get the correct TypeInfoMap
        langPK - the language PK of the properties, or null for unlocalized properties
        timestamp - the property timestamp of the item - the propert cache uses this to check later if it is uptodate

      • updatePropertyTypePKs

        public static void updatePropertyTypePKs​(TypeInfoMap infoMap,
                                         PK itemPK,
                                         PK newTypePK)
        changes all property data rows of one item to the new type pk. this will not invalidate any of its property caches - so make sure they are reloaded when the type has changed

      • writeProperties

        public static void writeProperties​(EJBPropertyRowCache prc,
                                   PK itemPK,
                                   PK typePK,
                                   TypeInfoMap infoMap,
                                   boolean localized)
        saves all changed properties of one property cache.
        Parameters:
        prc - the (modified) property cache
        infoMap - provides the correct columns and value classes for these properties

      • getChangeData

        for a modified property cache this puts together the list of columns, values and value classes. use these to build and fill you SQL statements.
        Parameters:
        infoMap - provides column names and value classes for properties
        prc - the modified property cache
        localized - tells if localized or unlocalized properties should be written - used for checking correctness of data
        con - the database connection
        Returns:
        ([column - name, value, ValueWriter ])
        Throws:
        java.sql.SQLException

        removes all property rows for a item.
        Parameters:
        itemPK - the item to remove properties for
