org.aksw.facete.v4.impl.FacetedRelationQuery
@Deprecated public class FacetedRelationQuery extends Object
Deprecated.
A faceted relation query is backed by a relation. Faceted queries can be started over each of its columns in order to constrain the matching rows. A faceted query is an intensional description of a set of resources, whereas if left unconstrained then the set of resources are those present in the column. Similar to SPARQL queries, which have CONSTRUCT and SELECT query forms, there are different ways for how to project the underlying bindings. COLUMNS is akin to select queries, where the projection is specified as a flat list of facet paths. TREE corresponds to a hierarchical table. In this format columns can not be arbitrarily arranged: It is only possible to reorder siblings.

      Convenience function if there is only a single root variable

    • availableRows

      public FacetedRelationQuery availableRows()
      Deprecated.
      Create a new faceted relation query with all constraints applied. The returned query's constraints are thus empty. The contained graph pattern may be used for querying or for further faceted search. This method is akin to FacetNode.availableValues()
