Rank Specific Rootnodes in CDM Classifications¶
The CDM library provides methods to select nodes of a classification at a specific rank as virtual rootnodes.
These are named in the CDM jargon Rank Specific Rootnodes. An exact match to taxon nodes for a given rank is
sometimes not possible. In this case the next lower taxon node will be chosen. Otherwise the section made through
classification at the given ranks would be incomplete.
This functionality is implemented in the method
ClassificationDaoHibernateImpl.listRankSpecificRootNodes(Classification classification, Rank rank, Integer limit, Integer start, List<String> propertyPaths, int queryIndex)
