getRootNode

public org.apache.jena.graph.Node getRootNode()

Description copied from interface: RootedQuery

The designated root node. The following rules apply:

• If getObjectQuery().getTemplate() is non-empty then the root node should be mentioned in the template.
• In case the template is empty then the root node should be a variable that occurs in getObjectQuery().getRelation().getElement(). Furthermore, if in this case the query is partitioned by a single variable then the root node should match that one.
