public interface QueryBuilder

A query specification. Once specified, call build(org.protempa.KnowledgeSource, org.protempa.AlgorithmSource) to build the actual query. It is recommended that you use Protempa.buildQuery(org.protempa.query.QueryBuilder), which calls this method with a Protempa instance's knowledge source backend and algorithm source backend.
