Examples of descend()

com.db4o.query.Query.descend()
returns a reference to a descendant node in the query graph.

If the node does not exist, it will be created.

All classes represented in the query node are tested, whether they contain a field with the specified field name. The descendant Query node will be created from all possible candidate classes. @param fieldName path to the descendant. @return descendant {@link Query} node
