net.mlw.vlh.adapter.util
Interface ObjectWrapper

public interface ObjectWrapper

This class is used in net.mlw.vlh.adapter.jdbc.objectWrapper.DefaultWrapperAdapter Using this wrapper you can replace record in valuelist with your record. Normally you select only ids and valulist is populated with the wrapped objects, that has selected id.

Using wrappers is recommended in cases, when your hibernate hql is too complex, and you cannot controll all composite joins. Then you would appreciate jdbc with the cunjuction of wrappers that allow you to call third party managers, that return you wanted object.

To pass additional parameters to the object wrapper, adapter will always set actuall ValueListInfo before calling getWrappedRecord method.

The ObjectToBeWrapped is determined in adapter. It this time it could be a ResultSet or one column of the record.
