Examples of org.openbp.core.model.item.ItemContainer

org.openbp.core.model.item.ItemContainer
The item container is a helper class for deserialization of item xml files. The problem is that an item can have different faces (for example an item can actually be a Java activity, a process activity etc.). When deserializing such an item from a file (that contains a single item only), the particular type of the item cannot be specified in the top-level xml element of a Castor mapping. Hence we wrap this top-level attribute in a container class that may specify the type of its content. Not pretty, but it works. @author Heiko Erhardt


    ItemTypeDescriptor itd = getItemTypeDescriptor(item.getItemType());
    if (itd.isContainedItem())
    {
      // Item is wrapped by a container class in its xml file
      obj = new ItemContainer(item);
    }


    // Dirty hack:
    // Castor doesn't support CDATA sections. So we write a dummy string and replace that
    // dummy string for the actual CDATA-escaped string when writing the xml to the file.
