Examples of org.openbravo.dal.xml.XMLEntityConverter

org.openbravo.dal.xml.XMLEntityConverter
Converts a XML string to an objectgraph with objects using Dom4j. This XMLEntityConverter can be used for smaller xml strings (less than 100mb). This XMLEntityConverter can handle OneToMany relations, this in contrast to the {@link StaxXMLEntityConverter}. During the XML parse phase this converter will match XML tags with new or existing (in the database) business objects. The matching logic is implemented in the {@link EntityResolver}.
The XMLEntityConverter keeps track of which objects are new, which exist but do not need to be updated or which objects exist but need to be updated.
This converter does not update the database directly. However, it changes the properties of existing objects. This means that a commit after calling the process method on the converter can result in database updates by Hibernate. @see Entity @author mtaal
