Class SqlPrePusher

java.lang.Object
org.aksw.jena_sparql_api.views.SqlPrePusher
public class SqlPrePusher extends Object
Methods of this class are invoked for each rdf-function after all its arguments have been pushed. TODO Rename to PostPush. Documentation below is outdated. ------------------------------------------------- Invoked on methods before a push is attempted. This gives us a chance to tranform for instance regex(term(id, lex, lang, dt)) into regex(lex) So basically it gives functions an opportunity to capture rdfterm arguments By default arguments are pushed first. TODO We need to identify different types of traversal (probably just child first (bottom up) and parent first (top down) and somehow allow to plug in the transformers
